kakak jawab pakai logika saja ya dek,,logika nya ada di gambar
nah jadi ½ lingkaran itu kan 180°,,jika di setengah lingkaran ada dua sudut dan sudut pertama sudah diketahui 113°,maka sudut yang satu nya lagi 180° - 113=67°
jadix=67°

6. The Lines Meet At the Point O. ANGLE AOC = 210° and ANGLE BOC = 254°. Find ANGLE AOB
See the question :
"The Lines Meet At the Point O. angle AOC = 220° and angle BOC = 254°. Find angle AOB = ... ?"
Discussion :
The first step. we have to know one circle. we subtract one circle with the angle BOC. and the result is the remaining angle
360° – 254° = 106°
second step. we subtract the angle of AOC with the remaining angle.
210° – 106° = 104°
So, angle AOB is a 104°
The model, we can see in the appendix below

9. the sides of parallelogram ABCD are represented as shown . find DA
Penjelasan dengan langkah-langkah:
Sifat jajar genjang:
AB \\ DC dan AD \\ BC sehingga AB = DC dan AD = BC
AB = DC
2x + 12 = 5x - 18
3x = 30
x = 10
karena AD = BC maka
AD = 3x - 6
= 3(10) - 6
= 24

14. the cell shown in the diagram has been magnified 3000 times. the diagram is 21 mm wide. what is the actual diameter of the cell?
The actual diameter of the cell based on the question above is 21/3000 mm or 0,007 mm. Setelah diperbesar sebanyak 3000 kali dan didapati ukuran diameter dari sell tersebut adalah 21 mm maka untuk menegtahui ukuran sebenarnya dari sell tersebut adalah dengan membagi ukuran setelah diperbesar dengan jumlah kali perbesaran. Oleh karena itu, didapati ukuranyya adalah 0,007 mm.
Pembahasan:
Sel adalah kumpulan dari materi yang paling sederhana yang hidup dan bagian penyusun makhluk hidup. Sel dapat melakukan aktivitas kehidupan dan reaksi kimia dalam mempertahankan kehidupan di dalam sellnya. struktur sel antara stuktur sel hewan dan tumbuhan berbeda beda. Struktur sel terdapat dua jenis yaitu struktur sel prokariot dan sel wukariot. Struktur sel prokariot adalah struktur sell yang tidak memiliki neukleus.sedangkan sel eukariot adalah struktur sel yang memiliki neukleus.Semua sel makhluk hidup memiliki membran plasma atau membran sel. Membran sel adalah lapisan paling luar yang melapisi dan menjaga komponen sel yang ada di dalamnya.Dinding sel adalah bagian sel yang hanya dimiliki oleh tumbuhan dan jamur. Pitoplasma memiliki 3 bagian utama yaitu: neukleus atau inti sel, sitoplasma, dan sitoskeleton.Pelajari lalebih lanjut

15. yg bisa bantuin yakk.. the sum of the three angles of triangle is 180degree. the sum of the angle is equal to the third angle and the difference of the two angles is equal to 2/3 the third angle. find the angles of this triangle
Misalkan sudut A,B,C
A=B
A+B=⅔C
A+B+C=180
1:1:3=180
maka
2A+3A=180
5A=180
A=180/5
A=36
A+B+C=180
36+36+C=180
C=180-72
C=108
Jadi sudut A=36, B=36 dan C=108

17. The polar ice park generally measures ?
you meant ‘Measurements of sea ice’
Well if it is : (Sorry if im wrong)
Sea ice extent is the area of sea with a specified amount of ice, usually 15%. To satellite microwave sensors, surface melt appears to be open water rather than water on top of sea ice. So, while reliable for measuring area most of the year, the microwave sensors are prone to underestimating the actual ice concentration and area when the surface is melting.[16]
Sea ice area Edit
To estimate ice area, scientists calculate the percentage of sea ice in each pixel, multiply by the pixel area, and total the amounts. To estimate ice extent, scientists set a threshold percentage, and count every pixel meeting or exceeding that threshold as "ice-covered." The National Snow and Ice Data Center, one of NASA's Distributed Active Archive Centers, monitors sea ice extent using a threshold of 15 percent.
Sea ice concentration Edit
Main article: Sea ice concentration
Sea ice concentration is the percentage of an area that is covered with sea ice.
Sea ice thickness Edit
Main article: Sea ice thickness
Sea ice thickness increases over time, and increases when winds and currents push the ice together. The European Space Agency's Cryosat-2 satellite was launched in April 2010 on a quest to map the thickness and shape of the Earth's polar ice cover. Its single instrument - a SAR/Interferometric Radar Altimeter is able to measure the sea ice freeboard.
Sea ice age Edit
The age of the ice is another key descriptor of the state of the sea ice cover, since older ice tends to be thicker and more resilient than younger ice. Sea ice rejects salt over time and becomes less salty resulting in a higher melting point.[5] A simple two-stage approach classifies sea ice into first year and multiyear ice. First-year is ice that has not yet survived a summer melt season, while multi-year ice has survived at least one summer and can be several years old. See sea ice growth processes.
Sea ice mass balance Edit
Measuring Sea Ice Mass Balance
Sea ice mass balance is the balance of how much the ice grows in the winter and melts in the summer. For Arctic sea ice virtually all of the growth occurs on the bottom of the ice. Melting occurs on both the top and the bottom of the ice. In the vast majority of cases all of the snow melts during the summer, typically in just a couple of weeks. The mass balance is a powerful concept since it is the great integrator of the heat budget. If there is a net increase of heat, then the ice will thin. A net cooling will result in thicker ice.
Making direct measurements of the mass balance is simple. An array of stakes and thickness gauges is used to measure ablation and accumulation of ice and snow at the top and bottom of the ice cover. In spite of the importance of mass balance measurements and the relatively simple equipment involved in making them, there are few observational results. This is due, in large part, to the expense involved in operating a long-term field camp to serve as the base for these studies.[18]
Sea ice volume Edit
Blue: Seasonal variation and long term decrease of Arctic sea ice volume as determined by measurement backed numerical modelling. Red: CryoSat-2 volume measurement (only October to April).
There are no Arctic-wide or Antarctic-wide measurements of the volume of sea ice, but the volume of the Arctic sea ice is calculated using the Pan-Arctic Ice Ocean Modeling and Assimilation System (PIOMAS) developed at the University of Washington Applied Physics Laboratory/Polar Science Center. PIOMAS blends satellite-observed sea ice concentrations into model calculations to estimate sea ice thickness and volume. Comparison with submarine, mooring, and satellite observations help increase the confidence of the model results.
ICESat was a laser altimeter equipped satellite, which could measure the freeboard of ice flows. Its active service period was from February 2003 to October 2009. Together with a set of auxiliary data like ice density, snow cover thickness, air pressure, water salinity one can calculate the flow thickness and thus its volume. Its data have been compared with the respective PIOMAS data and a reasonably agreement has been found.
Cryosat-2, launched in April 2010, has the ability to measure the freeboard of ice flows, just like ICESat, only that it uses radar instead of laser pulses. Data is calculated with the PIOMAS model.
