Question

two complementary angles differ by 12' find the angles

Answer 1

let one angle be x
and another be x-12
sum of complementary angles is:- 90°
x+x-12=90
2x=90-12
2x=78
x=39
therefore,1st angle is 39° and 2nd angle is x-12 i.e.
39-12=27°

Answer 2

Answer:

complementary angle

the sum of two angles is 90°

let the smaller angle be x°

bigger angle be x+12°

x+x+12=90°

2x=90-12

2x =78°

x = 78/2 = 39°

smaller angle =x = 39°

bigger angle x+12=39+12=51°..
