Question

Two complementary angles differ 12,find the angels?

Answer 1

The two complementary angles be X,90-X

Then,

90-X-X=12

90-2x=12

78=2x

X=39

Therefore angles are 39,51

Answer 2

Answer:

If 2 angles are complementary, their sum is 90.

Thus,

let the 1st angle be x and the other be (x-12)

A/Q,

x+(x-12)=90

2x-12=90

2x=90+12

2x=102

x=102/2

x=51

If angle x measures 51 degree, then the other angle is,

x=51

x= 51-12

x=31 degree.

Thus the required angles are of 51 degree and 31 degree.
