Answer 2

Answer:

Step-by-step explanation:

Let the 1st acute angle be x°

then the 2nd acut angle be (x - 12)°

A.T.Q.

90 + x + (x-12) = 180° [sum of interior angles]

=> 78 + 2x = 180°

=> 2x = 180 - 78

=> 2x = 102

=> x = 102 ÷ 2

Hence, x = 51

Now,

1st acute angle = x° = 51°

and, 2nd acute angle = x - 12

=>51° - 12°

=> 39°

Thus, two acute angles are 51° and 39°.
