Find ∠MPN

Help me please

Step-by-step explanation:

Line is a diameter of the circle because it passes through the circle's center O. Therefore, arc must be 180 degrees, as these are 360 degree in a circle.

We can then find the measure of arc :

Arc is formed by angle . Define an inscribed angle by an angle with a point on the circle creating an arc on the circumference of the circle. The measure of an inscribed angle is exactly half of the measure of the arc it forms.

Therefore, the measure of must be:

Similarly, the measure of must be:

Angles and form angle , which is one of the three angles in . Since the sum of the interior angles of a triangle add up to 180 degrees, we have:

square pyramid

step-by-step explanation:

square prism looks like nothing like that

triangular prism has a rectangular base instead of a square base

tetrahedron has a triangular base
