Question

Q4 The larger of two supplementary
angles exceeds the smaller by 40°.
Find the angles.

1. 100° 80°
2. 90°, 90°
3. 120°, 60°
4. 110°,70​

Answer 1

Answer:

4. 110°,70

Step-by-step explanation:

let the angles be x, x+40°

sum of two supplementary angles= 180°

x+x+40°=180°

2x+ 40°=180°

2x= 180-40°

2x=140°

x=140°/2

x= 70°

x+40°=70°+40°=110°

required angles are 70°,110°

answer

4. 110°,70
