Answer:
x is
Explanation:
Notice that angle 'x" is opposed via the vertex to the angle obtained by subtracting 150 degrees from 90 degrees (right angle), and therefore should be of the same measure.
Then:
see below
We can see the blue angle is 150° and is made up of 90° and something. That something is 150 - 90 = 60°. Since x and 60° are vertical angles, x = 60°.
