Question

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

Answer 1

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
