The difference between the measures of the two angles of a complementary pair is 40 degree. Find the measures of the two angles

Academic Mathematics NCERT Class 7

Let the angles be x,y.

We know that x+y = 90 (complementary angles)..................1

Given: x-y = 40 degree............2

Add 1 and 2 =>

2x = 130

x = 65

Substitute x in 1

y = 90-65 = 25

The measures of the angles are 65 and 25 degrees.
