Yo Directrix u there

Let one of the two angles be x

The second angle is 80% of x or .8x

Complementary angles sum to 90.

That means, in this problem, that x + .8x = 90

@adamarbour 

Your task is to solve the equation x + .8x = 90 for x.

Then, substitute the value of x to get the size of the smaller angle.
