Answer: x = 25

Step-by-step explanation:

If these angles are congruent, that means they are equal. Using that information, we can frame the following equation:

(x+15) = (3x-35)

To find 'x', we just need to solve the above equation.

(x+15) = (3x-35)

x+15 = 3x-35

x-3x = -35-15

-2x = -50

x = 25.

Therefore, 'x' is 25 degrees.
