Answer 1

Given:

Two angles are supplementary, and the larger angle is 28º more than the smaller angle.

Formula used:

If two angles are supplementary, their sum is 180º.

Let the smaller angle be x.

Larger angle = x + 28º

Calculation:

Sum of angles = x + (x + 28º) = 180º

⇒ 2x + 28 = 180

⇒ 2x = 180 - 28

⇒ 2x = 152

⇒ x = 76º

∴ The correct answer is option (4).
