5. 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
6. 522. Find the size of the angle supplementary to: a) 152b) 151"c) 13°
Jawaban:
a. 28°
b. 29°
c. 167°
Penjelasan dengan langkah-langkah:
suplementary it means a° + b° is equal to 180°
a) 152 + b = 180°
b = 28°
b) 151° + b = 180°
b = 29 °
c) 13° + b = 180
b= 167°
7. Solve for x and find the measure of the bold angle
[tex]16x - 6 = 14x + 6 \\ 16x - 14x = 6 + 6 \\ 2x = 12 \\ x = \frac{12}{2} \\ x = 6 \\ \\ bold \: angle \\ 14x + 6 \\ 14.6 + 6 \\ 84 + 6 \\ 90[/tex]
8. Use the formula for sn to determine how many terms of the series must be added to give the sum indicated 1+2+3+. . . .=210
[tex]1+2+3+\cdots=210[/tex] merupakan deret aritmatika dengan [tex]a=1[/tex] dan [tex]b=1[/tex]. Rumus jumlah untuk deret aritmatika tersebut adalah:
[tex]S_n= \frac{n}{2}(2a+(n-1)b) [/tex]
Selanjutnya substitusikan nilai-nilai yang diketahui pada rumus jumlah diatas, yaitu:
[tex]210= \frac{n}{2} (2\times1+(n-1)\times1) \\ 210=\frac{n}{2} (2+n-1) \\ 210=\frac{n}{2} (1+n) \\ 420=n+n^2 [/tex]
solusi dari persamaan diatas adalah [tex]n=20[/tex] atau [tex]n=-21[/tex], jadi yang paling mungkin adalah [tex]n=20[/tex].
Dari sini bisa disimpulkan bahwa banyaknya suku ada 20, sehingga banyaknya sukuyang harus ditambahkan pada deret diatas agar jumlahnya 210 adalah 17 suku.

11. 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

14. Find the angle a, b, c and d on the figure.
a = 35° ; b = 50°
c = 85° ; d = 30°
Note
Sum of the angle on triangle is 180°Straight line has 180°Find a
80° + a° + 65° = 180°
a = 180° - 80° - 65°
= 35°
Find b
a° + b° + 95° = 180°
35° + b° + 95° = 180°
b = 180° - 35° - 95°
= 50°
Find c
95° + c° = 180°
c = 180° - 95°
= 85 °
Find d
65° + c° + d° = 180°
65° + 85° + d° = 180°
d = 180° - 85° - 65°
= 30°
15. Find the number of moles of the indicated species: a) 333 mg of Na2B4O7.10H20
Jawaban:
Penjelasan:
[tex]\text{Na}_2\text{B}_4\text{O}_7.10\text{H}_2\text{O}[/tex]
Mr = 2Na + 4B + 8O + 20H
Mr = 2(23) + 4(11) + 17(16) + 20(1)
Mr = 46 + 44 + 272+ 20
Mr = 382
[tex]n = \frac{m}{Mm}\\n = \frac{333}{382}\\n = 0,87 \times 10^-3 \ \text{mol}[/tex]

18. Find the unknown marked angle in each of the Isosceles triangles.
karena DF dan EF sama panjang, maka sudut D dan sudut E sama besar.
EF = DF = 53°
Untuk menghitung sudut F maka
180° - 53° - 53° = 74°
Semoga membantu ;)
