Diketahui:
sudut DCE = 30°
sudut CDE = sudut siku-siku = 90°
DItanya: sudut CED = ....???
Jawab:
∠CED = 180° - (∠DCE+∠CDE)
∠CED = 180° - (90° + 30°)
∠CED = 180° - 120°
∠CED = 60°
Jadi, besar sudut CED adalah 60°

Jadi, besar sudut CED adalah
180° - (30° + 90° (karena siku-siku))
= 180° - 120°
= 60°
