Answer:

90 degrees and 40 degrees

Step-by-step explanation:

When finding angles of a triangle within a semicircle the triangle would usually be a right triangle. One common fact about right triangles is always that they have 90-degree angles, one common fact about triangles angles in general is that all three angles add up to 180 degrees.

So, if we have 50-degree angle and a 90-degree angle:


180-90=90

90-50=40

=40

Therefore, your three angles are "50, 90, and 40 degrees."

Hope this helps.
