Answer:

67.5°

Step-by-step explanation:

The given angle is 45°, so the remaining to angles must collectively make up the rest of the 180°. In this situation, the opposite sides are congruent, and therefore the angles are identical. So, from the remaining 135° that need to be accounted for, we would simply divide by 2, and get 67.5°.
