Answer 1

Answer:

The angles are 39 , 51 degrees respectively

Step by step explanation :-

Let one of angle be x .

Two complementary angles differ by = 12.

Bigger angle = ( x + 12 ).

Complementary angles = 90

x + x + 12 = 90

2x + 12 = 90

2x = 90 - 12

2x = 78

x = 78 / 2

x = 39

x = 39 = smallest angle

( x + 12 )

= 39 + 12

= 51 ( biggest angle ).

The angles are 39, 51 degrees respectively.

please mark me as brilliant.
