Find the value of in each quadrilateral. 4. X ???
1. Find the value of in each quadrilateral. 4. X ???
penyelesaian :
-6x + 2 = 360 - ( 75 + 103 + 96 )
-6x + 2 = 360 - 247
-6x + 2 = 113
-6x = 113 - 2
-6x = 111
x = 111 + 6
x = 117°
2. 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°3. 17. Cari nilai x bagi setiap yang berikut.Find the value of x in each of the following

8. find the value of the unknown in each of the following figures. plis help part b.
Jawab:
sudut A = 108°
Sudut B = 144°
Penjelasan dengan langkah-langkah:
Rumus menghitung Jumlah derajat dari sudut bangunan
(n-2) x 180°
dengan n = jumlah sisi
diketahui gambar tersebut merupakan heksagon (6 sisi)
berarti jumlah sudutnya adalah (6-2) x 180 = 4 x 180 = 720°
122 + 128 + 114 + 104 + 3b + 4b = 720
468 + 7b = 720
7b = 252
b = 36
maka sudut A = 3 x (36) = 108°
sudut B = 4 x (36) = 144°

10. Find the value of x in the figure below.
Jawaban:
2x + 5x + 3x + 90° = 360°
10x + 90° = 360°
10x = 360° - 90°
10x = 270°
x = 270°/10
x = 27°
11. find the value of each of the following 0.8% of 4.5m
Jawab:
we can use the formula:
percentage/100 x value = result
So, for this case:
0.8/100 x 4,500,000 = 36,000
Therefore, 0.8% of 4.5 million is equal to 36,000.

14. 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°

17. In each of the following, AOB and COD are straight lines. Find the value of x
a. Nilai [tex]x[/tex] pada gambar 1 adalah [tex]18^o[/tex]
b. Nilai [tex]x[/tex] pada Gambar 2 adalah [tex]33^o[/tex]
Diketahui :Gambar 1
∠AOC = [tex](x + 20)^o[/tex]
∠BOD = [tex]38^o[/tex]
Gambar 2
∠AOE = [tex]2x^o[/tex]
∠DOE= [tex]57^o[/tex]
∠BOC = [tex]123^o[/tex]
Ditanyakan :a. Nilai [tex]x[/tex] pada gambar Bagian 1
b. Nilai [tex]x[/tex] pada gambar Bagian 2
Jawab :a. Menentukan nilai x pada Gambar 1
Perhatikan ∠AOC dan sudut ∠DOE
∠AOC = ∠DOE (sudut bertolak belakang), maka
[tex](x + 20)^o[/tex] = [tex]38^o[/tex]
⇔ [tex](x + 20)^o[/tex] = [tex]38^o[/tex]
⇔ [tex]x[/tex] = [tex]38^o - 20^o[/tex]
⇔ [tex]x[/tex] = [tex]18^o[/tex]
∴ Jadi Nilai [tex]x[/tex] pada gambar 1 adalah [tex]18^o[/tex]
b. Menentukan nilai [tex]x[/tex] pada gambar 2
Perhatikan ∠AOE dan ∠EOD
∠AOE + ∠EOD = ∠AOD
⇔ [tex]2x^o[/tex] + [tex]57^o[/tex] = ∠AOD
Maka ∠AOD = [tex]2x^o[/tex] + [tex]57^o[/tex]
Perhatikan ∠AOD dan ∠BOC
∠AOD = ∠BOC (sudut bertolak belakang)
⇔ ∠AOD = ∠BOC
⇔ [tex]2x^o[/tex] + [tex]57^o[/tex] = [tex]123^o[/tex]
⇔ [tex]2x^o[/tex] = [tex]123^o[/tex] - [tex]57^o[/tex]
⇔ [tex]2x^o[/tex] = [tex]66^o[/tex]
⇔ [tex]x^o[/tex] = [tex]\frac{66}{2}[/tex]
⇔ [tex]x^o[/tex] = [tex]33^o[/tex]
∴ Jadi Nilai [tex]x[/tex] pada Gambar 2 adalah [tex]33^o[/tex]

maaf kalau salah
20. Find the value of x in the figure below.
X + 12° + (180° - 43°) = 180°
x + 12° + 137° = 180°
x + 149° = 180°
x = 180° - 149°
X = 31°
Maaf klo ada yg salah
