They are complementary, so they add to 90°. If the ratio is 4:1, they must be 4/5 and 1/5 of the total repectively, so they must be 4/5 (90) = 72° and 1/5 (90) = 18°.

let x be the first angle then 4x is the second angle
complementary angles add to 90 degress
x + 4x = 90
5x = 90
x = 18
so the two angles are 18 degrees and 72 degress

the different answer became close, yet incorrect. Complementary angles upload as much as ninety, so only carry on with the stairs yet upload them as much as ninety; supplementary angles are those that upload as much as a hundred and eighty.
