The two acute angles total 90 degrees. If the larger angle is 4 times the smaller angle, then the smaller angle is 18 degrees and the larger angle is 72 degrees (4 x 18 degrees).
Since they add up to 90, the smaller angle is 90(1/5) =18 degrees, and the larger angle is 90(4/5)=72 degrees.
the two acute angles have a sum of 90. If the ratio is 4:1, then there are five units to split. Divide the 90 degrees by 5.90/5 = 1818 * 4 = 72So the larger angle has a measure of 72 degrees and the smaller angle is 18 degrees.

Complementary angles are angles that add up to 90 degrees. If the smaller angle is x, the larger is 5x, so 6x = 90. X equals 15, and the larger angle measures 75 degrees.

Could be a 90-60-30 degree triangle. so, 60 degrees.
Two supplementary angles add up to 180 degrees. If one measures 60 less than the other, they must be 60 and 120 degrees, so the measure of the larger angle is 120 degrees. To find that algebraically, where m is the larger angle: m+(m-60)=180 2m=240 m=120
