Answer:
90 degrees and 40 degrees
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:
[tex]180-90=90[/tex]
[tex]90-50=40[/tex]
[tex]=40[/tex]
Therefore, your three angles are "50, 90, and 40 degrees."
Hope this helps.
