Jawaban:
a. a + a + 20° = 90°
2a + 20° = 90°
2a = 90° - 20°
2a = 70°
a = 70°/2
a = 35°
b. <QOR = a + 20°
= 35° + 20°
= 55°
c. <SOU = 180° - 55° - 40°
= 85°

A) NILAI A :
(A + A) + 20° = 90°
(1 + 1)A = (90 - 20)°
2A = 70°
A = (70/2)°
A = 35/1
A = 35°
B. <QOR :
= (35 + 20)°
= 55°
C. <SOU :
= (180 - 55 - 40)°
= (125 - 40)°
