2. A rhombus has diagonals of length 8 cm and 11 cm. Find the measure of the smaller angles of the rhombus.
Dua buah diagonal belahketupat saling berpotongan di sebuah titik yang berada tepat di tengah masing-masing diagonal.
Sudut yg lebih kecil dari belahketupat ( β ), adalah sudut yg bersinggungan dengan diagonal yg lebih panjang.
Sehingga dengan perbandingan trigonometri didapatkan :
tan ½β = ½ x 8 / ½ x 11
tan ½β = 4 / 5,5
tan ½β = 0,7272727273
½β ≈ 36° (nilai pembulatan)
==> β = 72°
3. the sum of three angles of triangle of 180 deg. the sum of two of the angles is equal to the third angle and the difference of the two angles is equal to 2/3 the third angles find the angles of this triangle?
suppose that :
x = first angle
y = second angle
z = third angle
The sum of three angles of triangle of 180°
So :
x + y + z = 180
The sum of two of the angles is equal to the third angle
So :
x + y = z
The difference of the two angles is equal to 2/3 the third angles
So :
x - y = (2/3) z
subtitute x + y = z
x + y + z = 180
z + z = 180
2z = 180
z = 180/2
z = 90
x + y = z
x + y = 90
x - y = (2/3) z
x - y = (2/3) (90)
x - y = 60 >>> x = 60 + y
subtitute x = 60 + y
x + y = 90
60 + y + y = 90
60 + 2y = 90
2y = 90 - 60
2y = 30
y = 30/2
y = 15
x = 60 + y
x = 60 + 15
x = 75
We got :
x = 75
y = 15
z = 90
So, the angles are 75°, 15°, and 90°

6. If the angles of a triangle are inthe ratio 1:3:5, then how many degrees are in the measure of the smalest angle?
Jawaban:
22.5 degrees
Penjelasan:
one triangle has total of 360 degrees
so :
one plus three plus five equals eight
small angle of triangle has a ratio 1 of 8 (1/8)
1/8 . 180 = 22.5 degrees

9. aku ada pertanyaan matematika nih tp pake bahasa inggris . ada yag bisa bantu gk ? ini soalnya 1. the sum of the three angles of a triangle is 180degree. the sum of two of the angles is equal to the third angle and the difference of the two angles is equal to
jumlah dari tiga sudut segitiga adalah 180 derajat . jumlah dua sudut sama dengan sudut ketiga dan perbedaan dari dua sudut sama dengan...
misal sudutnya : a + b + c = 180
a + b = c
a + b - c = 0
eliminasi diperoleh
2c = 180
c = 90
a + b = 90
a = 90 - b

(1) dua pasang sudut yang bersesuaian sama besar,
(ii) dua pasang sudut yang sama besar,
(iii) dua pasang sudut dalam yang bersuplemen.
(b) Apakah BWQ = AXR? Jelaskan jawabanmu.
c) Apakah jumlah DYP dan CZR sama dengan 180? Jelaskan jawaban Anda
Garis dan SudutJawaban
A.
(i) 2 Pasang sudut yang bersesuaian sama besar adalah
< W = < X
< Y = < Z
(ii) 2 Pasang sudut yang sama besar
< W = < X
< Y = < Z
(iii) 2 Pasang sudut dalam yang tambahan
< YWX dan < ZXW
< WYZ dan < XZY
B. BWQ = AXR
Tidak sama karena < BWQ lebih landai dibandingkan dengan < AXR yang lebih lancip
C. DYP + CZR = 180⁰
Ya, karena < DYP dan < CZR saling berhadapan maka jumlah kedua sudut adalan 180⁰

18. 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
