Answer:
The other two angles are 90° and 40°

Explanation:
When a triangle is inscribed in a semi-circle, this triangle is usually a right-angled triangle (check attached image).
This means that we have one of the angle = 90°

Now, we know that the sum of angles in a triangle is 180.
This means that:
180 - 50 + 90 + measure of third angle
measure of third angle = 180 - (90+50)
measure of third angle = 40°

Hope this helps :)
