What is the measure of an angle, if three is subtracted from twice the supplement and result is 297 degrees?

45°

30°

90°

None of these

Let's denote the angle as x. The supplement of x is 180 - x.

Given "three is subtracted from twice the supplement" equals 297:

2(180 - x) - 3 = 297

Expanding the equation:

360 - 2x - 3 = 297

357 - 2x = 297

Solving for x:

-2x = 297 - 357

-2x = -60

x = 30
