5. 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 ;)
6. find the value of x and y in each of the following
a + x = 360°
a = 360° – x
a + 31° + 31° = 180°
(360° – x) + 62° = 180°
360° + 62° – 180° = x
242° = x
x = 242°
68° + (y + 31°) + (y + 31°) = 180°
2(y + 31°) = 180° – 62° = 118°
[tex]y + 3 {1}^{0} = \frac{11 {8}^{0} }{2} = 5 {6}^{0} [/tex]
y = 56° – 31°
y = 25°7. Find x and y in the following rhombus
Jawab:
x = 12 dan y = 7
Penjelasan dengan langkah-langkah:
Diketahui: m∠BAC = 4x°, m∠B = 12y°, m∠D = 7x°
Ditanya: x dan y...?
Jawab:
Bangun tersebut adalah rhombus/layang-layang. Artinya:
m∠A = m∠C
m∠B = m∠D
m∠D = 7x
m∠B = m∠D
m∠B = 7x
Belah ketupat memiliki simetri lipat 2, salah satunya garis AC, sehingga ΔABC = ΔADC
Artinya,
12y = 7x (Persamaan (i))∠BAC = ∠CAD = 4x°
m∠A = ∠BAC + ∠CAD
m∠A = 4x + 4x
m∠A = 8x
m∠A = m∠C
m∠C = 8x
m∠A + m∠B + m∠C + m∠D = 360°
8x + 7x + 8y + 7x = 360°
30x = 360°
x = 12
Berdasarkan persamaan (i):
12y = 7x
12y = 7(12)
12y = 84
y = 84/12
y = 7
Kesimpulan: Nilai x dan y berturut-turut adalah 12 dan 7
Sekian penjelasan dari saya, mohon maaf apabila ada salah kata. Terimakasih :)

9. Find the value of the unknown in each of the following figures
mboh aku gk ngerti ju woyyyyyy
10. . Find the unknown angles in each square and rectangle.
Jawaban:
1. a = 90°
b = 90-30-15 = 45°
2. egh = 90-25 = 65°
hgj = 180-65-57 = 58°
fgk = 180 - 65 = 115°
11. find the size of the unknown angles in each diagrams
Jawaban:
360° = 120° + 92° + 65° + X°
360° = 212° + 65° + X°
360° = 277° + X°
360° - 277° = X°
83° = X°
So, The Unknown Angles In X Is 83°

12. find the value of the unknown in each of the following figures
b). Besarnya sudut segitiga sama kaki 180°
maka,
<a + <b + <c = 180°
68° + 64° + 2b° = 180°
132° + 2b° = 180°
2b = 180° - 132°
2b = 48°
b = 24°
d). <ABC = 180°
maka,
<a + <b + <c = 180°
3d° + 4d° + d° = 180°
8d° = 180°
d = 180° / 8°
d = 22,5°
f).<ABC = 180°
maka,
<a + <b + <c = 180°
f° + f° + f° = 180°
3f° = 180°
f = 180°/3°
f = 60°
13. Find the unknown marked angles in each of the right-angled triangles.tolong bantu dong
Jawab:
a. 180° - (90° + 57°)
180° - 147°
= 33°
b. ∠ABC = 180° - (90° + 28°)
= 180° - 118°
= 62°
∠ADC = 180° - {90° - (90° - 28°)}
= 180° - (90° + 62°)
= 180° - 152°
= 28°
c. ∠GEF = 180 - (90 + 26)
= 180 - 116
= 64
∠DEG = 90 - 64
= 26

17. 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°
18. 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°
