Question

Answer the unknown Angles
​

Answer 1

p=45°, q=45°, s=112.5°

Explanation:

Because the triangle is an isosceles right triangle,
`p=q=45^(\circ)`.

In the top triangle, because of the isosceles triangle, the other two angles are each 67.5°.

Therefore, because angles that add to form a straight angle add to 180°, s=112.5°.
