As we know from the figure, the lower left interior angle is x degrees and the top interior angle is 30 degrees.

Since the sum of the interior angles in a triangle is always 180 degrees, we can set up the equation:
x + 30 + 90 = 180

Simplifying the equation, we have:
x + 120 = 180

Subtracting 120 from both sides, we get:
x = 180 - 120
x = 60

Therefore, the value of x is 60 degrees.
