Please help me with this math problem!

Step-by-step explanation:

Since the two lines running left to right are parallel, and cut into the right side of the triangle, the angles and are equal.

With this information, we can solve for :

Now that we know , we can determine what the actual value of these angles are:

or

Now, we see that the top line of the two parallel lines cuts the right side of the triangle into two angles, and . Since it's cutting a straight line into two angles, we know that the same of these angles must be °. We already solved for the top angle and found that it is °, so that means the bottom angle is °. With this, we can solve for :

Therefore, the answer is
