Question

angles a and b are complementary if the measure of angle A is 27 degrees more than measure of angle b, what is the measure of angel b ?

Answer 1

Complementary angle= two angle whose sum is 90°
a= x +27
b= x
2x+27=90°
2x= 90-27
2x=63
x=63/2
x= 31.5 or 31°30'
b= 31°30' 
a= 31.5+27= 58.5---->58°30'
