Answer:

∠2 = 152

Step-by-step explanation:

A straight angle should always equal 180, and that is really the key to how we answer this problem. That means that ∠1 and ∠2 are supplementary, and add up to 180°.

That means that 180-28, will give us our other angle.

Answer:

152°

Step-by-step explanation:

Angles on a straight line add up to 180°

Angle 2 + 28 = 180

Angle 2 = 180 - 28

= 152°
