Question 324597
let the angle be x
the complement will be 90-x
..
the supplement will be 180-x
..
four times the complement = 4(90-x)
Add 15 to it
4(90-x)+15 = 180-x
360-4x +15=180-x
-4x+x=-360-15+180
-3x=-195
x=-195/-3
x= 65 deg
The complement = 90-65=25 deg
the supplement of the angle = 180 -x=180-65=115 deg
