Question

The difference in the measure of two complementary angle is 12 degree. Find the measure of the angle

Answer 1

Answer.Let one angle be x

it's complementary. =(90-x)

according to question

x-(90-x)=12

x-90+x=12

2x=12+90=⟩102

x=102/2

x=51°

therefore,it's complementary=(90-x)=90-51=39°
