Answer:
15,75,90
Explanation:
the 2 acute angles of a right triangle add to 90 degrees
the other angle is a right angle which equals 90 degrees
lets call them x and y
x = 5y one is 5 times the other
x+y = 90
substitute x=5y
5y+y =90
combine like terms
6y =90
divide each side by 6
y = 90/6
y = 15
x = 5*y
x = 5*15
x = 75
the three angles are x, y, right angle
75, 15, 90
put them in order from smallest to largest
15,75,90
