Angle abc is 10 more than its complement. what is the measure of angle abc?

Complementary angles are angles whose sum is equal to 90. so let the x be the complement angle of angle abc

and y be the angle ABC

since

Angle abc is 10 more than its complement

y = x + 10

x + x + 10 = 90

2x = 80

x = 40

y = 50
