Answer 2

Answer :

If the two angles are complementary that means their sum is equal to 90 degree .

Let one of the angles be x ,

Given : the other angle is $\dfrac{4}{5}x$

So now add these ,

= x + $\dfrac{4}{5}x$ = 90

Multiply both sides with 5 ,

= 5x + 4x = 450

= 9x = 450

= x = $\dfrac{450}{90}$

= x = 50
