WebA tangent makes an angle of 90 degrees with the radius of a circle, so we know that ∠OAC + x = 90. The angle in a semi-circle is 90, so ∠BCA = 90. The angles in a triangle add up to 180, so ∠BCA + ∠OAC + y = 180 … WebSep 4, 2024 · Solution. By Theorem 7.3. 3, A P = B P. So A B P is isosceles with ∠ P A B = ∠ P B A = 75 ∘. Therefore x ∘ = 90 ∘ − 75 ∘ = 15 ∘. Answer: x = 15. If each side of a polygon is tangent to a circle, the circle is said to be inscribed in the polygon and the polygon is said to be circumscribed about the circle.
