x = 90

Step-by-step explanation:

A line will ALWAYS equal 180 degrees, so we know that one angle is <90 and we have to find x, which is the other angle of the line.

So, x + 90 = 180

You can either solve the equation for x or you can just subtract 90 from x, which is the easier way.

180 - 90 = 90

So, x = 90

I hope this helps, and explains it!
