Question

the supplement of an angle is less than three times its compliment by 20* . find the angle

Answer 1

Answer:

let angle be X

so suplymentry angle is= 3 x-20

X + (3 x-20)= 180

4x-20. =180

4x= 180+20

4x=200

X=200/4

X =50

so that angle is 50

suplymentry angle is

(3 x-20)

50× 3-20

150-20

130
