Question

Tolong jawab pake cara yaaa, trims hehe

Answer 1

Pengerjaannya harus beruntut yaa hehe

*
180 - 44 = 8y
136 = 8y
y = 136 / 8
y = 17°

**
180 - 8y = 2 z
180 - 8 x 17 = 2 z
180 - 136 = 2 z
z = 44 / 2
z = 22°

*** mencari sudut yang diatas segitiga
180 - 78 - 2z
= 102 - 2 x 22
= 102 - 44
= 58°

besar sudut sebelah kanan 3x ↓
= 180 - (44 + 58)
= 180 - 102
= 78°

180 - 78 = 3x
102 = 3x
x = 102 / 3
x = 34°


*********
x + y + z
= 34 + 17 + 22
= 73°
