2x + x + 2² + x = 90°
4x + 22° = 90°
4x = 90° - 22°
x = 68°/4
= 34°/2
= 17°
<CBD = 2x
= 2×17°
= 34°
➜ Jadi besar sudut CBD adalah C. 34° ✔

Jawaban:
KARENA MEMBENTUK SUDUT SIKU-SIKU MAKA HASILNYA PASTI 90°
2X° + (X + 22)° + X° = 90
(2X + X + X) + 22 = 90
4X + 22 = 90
4X = 90 - 22
4X = 68
X = 68 : 4
X = 17
2X° = 2(17) = 34°
JAWABANNYA C
