Answer:
Step-by-step explanation:
Sum of supplementary angles= 180°
Measure of smaller angle= x°
Measure of larger angle= (x+40)°
⇒ x°+(x+40)°= 180°
= 2x+40°= 180°
= 2x= 180°- 40°
= 2x= 140°
= x°= 140°/2
= x°= 70°
Smaller angle= 70°
Larger angle= (x+40)°
= (70+40)°
= 110°
VERIFY:
70°+110°= 180°
180°= 180°
LHS= RHS
Hence, verified
