Answer 2

Given : measure of an angle of a parallelo-gram is half its complementary angle,  

To Find : the complementary angle  

Solution:

Two angles that sum to one right angle (90°) are called complementary angles.

Let say Angle is A

Then complementary angle = 90° - A

A = (90° - A )/2

=> 2A = 90° - A

=> 3A = 90°

=> A = 30°

complementary angle = 90° - A  =  90°  - 30°   = 60°

complementary angle  60°
