Bantu gw yak :3 xixixixi

» Jawaban:

d. 96°

» Penyelesaian Soal:

Diketahui:

<A = 2x
<B = 20°
<C = 3x
Total Sudut Segitiga = 180°

Ditanya:

Besar <C?

Dijawab:

⏺ Nilai x

$boxed{ begin{array}{clclc} sf angle a + angle b + angle c = total : sudut : segitiga \ 2x + 20 + 3x = 180 \ 5x + 20 = 180 \ 5x = 180 - 20 \ 5x = 160 \ x = 160 div 5 \ x = 32 end{array}}$

~~~~~~~~~~~~~~

⏺ Besar <C

$boxed{ begin{array}{clclc} angle c = 3x \ angle c = 3(32) \ angle c = 3 times 32 \ boxed {huge angle c = 96} end{array}}$

~~~~~~~~~~~~~~

Kesimpulan:

Besar Sudut C adalah 96° ( Opsi D).

Jawaban:

3x + 2x + 20 = 180

5x = 180 – 20

5x = 160

x = 32

C = 3x

3 x 32 = 96
