Question

an angle is 30 degree less than two times its supplement find the angle​

Answer 1

x = angle measure in degrees

---

2(180 - x) - 30 = x

360 - 2x - 30 = x

3x = 330

x = 110.

please mark my answer as brainlist answer if it right.

Answer 2

Answer:

x+y=180

let x=2y-30

putting the value of x in above equation

2y-30=180

2y=210

y=210/2

y=105

now x+105=180

x=180-105

x=75
