Question

in two complementary angles one of the angle is four times the remaining angle then find the two complementary angles

Answer 1

let the angle be y.
remaining angle = 90-y
4 times the remaining angle= 4(90-y) = 360-4y
ATQ, 360-4y+y = 90 
-3y = 90-360
-3y = -270
y= -270/-3
y=90
remaining angle = 360-4y = 360-4(90) = 0
