4. Inscribed Angles and Polygons
Sign In
You can find x using the second part of the Inscribed Right Triangle Theorem.
x=30, y=28
We are given the following diagram and asked to find the value of variables x and y.
Inscribed Right Triangle Theorem |
If a right triangle is inscribed in a circle, then the hypotenuse is a diameter of the circle. Conversely, if one side of an inscribed triangle is a diameter of the circle, then the triangle is a right triangle and the angle opposite the diameter is the right angle. |
