Answer:
37.5 degrees
Explanation:
there are two isoceles triangles. we know that an isoceles triangle has 2 congruent angles. since we know that the first angle is 75 degrees, we subtract 75 from 180 (since the three angles of a triangle add up to 180). Then, we take the difference (105) and divide it by 2 to get 52.5. since we know x and the angle we just found (52.5) are complimentary, we subtract 52.5 from 90 to get x = 37.5 degrees.
