an angle is 4 times of its complementary angle. find an angle and its supplementary angle
amalpriya72:
take the angle = x , so 4x = 90-x their for 5x = 90 , x=90/5 ie x = 18.. the supplementary of this angle is 180- 18 = 162

take the angle as "x"
four times of this angle = 4x
its complimentary angle = 90-x
4x = 90-x
5x = 90
x = 90/5
x= 18
4x , ie 4*18 = 72
its supplementary angle = 180-72
=108
Ur ans. is right but 18 multiply with 4 = 72 and supplementry angle is 180-72=108
oh sry its my fault i forgot to multiply
thank u
Mostly welcome
