The sum of adjacent angles on a straight line would be 180°.

Since x is on a straight line,what we need to do is to deduct the remaining two angles,here's what the equation would be like:

180°-90°-30°
=60°

Thus,x=60°

hope it helps!

Hello!

The angle is a straight angle, which measures 180°.

One angle is a right angle, which measures 90°, while the other angle measures 30°.

90 + 30 = 120

That means x = 180 - 120. To find x, subtract 120 from 180

180 - 120 = 60
