Answer:
Smaller angle in equal to... 80°
Step-by-step explanation:
Linear pair = 180°
ratio of angles = 4:5
∴ Angles = 180° ÷ (4+5)
= 180° ÷ 9
= 20°
Angle in the ratio 4 = 20° × 4
= 80°
Angle in the ratio 5 = 20° × 5
= 100°
CHECK
80° + 100° = 180°
checked
Smaller angle in equal to...
80° < 100°
= 80°
