Astudent inscribes a triangle within a semicircle what is the measure of mmo a: 180 degrees b: 120 degrees c: 60 degrees d: 90 degrees

Solution:

Must keep in mind: Angle in a Semicircle is a right Angle.

If  one Side of Triangle is along the Diameter and the other two sides intersect at a point on the circle, then angle between those two sides which intersect at a point on the circle measures 90°.

Measure of that angle will be of 90°.

Option D: 90 degrees
