Let the measure of smaller angle = x

According to the condition,

the measure of larger angle = x + 40
We know that sum of the supplementary angles is equal to 1800
 
→ x + x + 40 = 180
→ 2x = 140
→   x = 70
 
The measure of smaller angle = x = 700 and the measure of larger angle = x + 40 = 70 + 40 = 1100
