Complement of angle A is 20 degrees less than half the supplement of angle A. Find the measure of angle A
X be the angle A
Complementary angle = 90-x
Supplementary angle =180-x
90-x =1/2 (180-x) -20
90-x = 90-1/2x -20= 70 -1/2x
20 =1/2 x 1/2 x= 20 x=40
Verification 50 = (180-40)/2-20= 70-20 .............. (40 Degrees)
