Answer:

B or 108

Step-by-step explanation:

we know that the line splits the 90 angle, so the other side is 54

Since it is a isosceles triangle, the base angles are the same and they are both 54 degrees.

The sum of all the angles in a triangle is 180, so 180-54-54 is 72.

Since the line intersecting the triangle is a straight angle 180, we do 180-72=108
