Question

one third of an angle is equal to its supplement the measure of this angle is​

Answer 1

Answer:

let the measure of angle be X

so,one third of angle = 1/3ofx

so, 1/3*X+X=180°

1/3*2x=180°

2x=180*3/1

2x=540/1

2x=540

X = 540/2

X=270

Answer 2

Answer:

Supplement angle =180

Let the angle be x then,

X/3 + (180-x)=180

X=135(45*3)

Therefore,the angles are

135 and 45
