Question

(a)An angle measures 41 degrees. What is the measure of its complement?

Answer 1

(a) An angle and its complement add to 90°.

... 41° + complement = 90°

... complement = 49° . . . . . . . . subtract 41° from both sides of the equation

(b) An angle and its supplement add to 180°.

... 35° + supplement = 180°

... supplement = 145° . . . . . . . . . subtract 35° from both sides of the equation
