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
