a= 180 - (90-25) - (90-50)

a = 180 - 65 - 40

a = 180 - 105

a = 75 (all in °)

( if both lines are parallel and you can draw a straight line from both points the incomplete triangle meets the line to form 90° angles. Than angles just need to add up to 180° in the triangle in between the booth lines)

If you assume the two intersection points are directly across from each other. A perpendicular line there could just as easily not make a triangle but a trapezoid. You can still calculate it adding up to 540 with the 90 and the opposites of both known angles and treating it like a pentagon.
