### Example Question #4 : Triangles

A right triangle has a hypotenuse of 10 and a side of 6. What is the missing side?

**Possible Answers:**

**Correct answer:**

To find the missing side, use the Pythagorean Theorem . Plug in (remember c is always the hypotenuse!) so that . Simplify and you get Subtract 36 from both sides so that you get Take the square root of both sides. B is 8.

### Example Question #2 : Right Triangles

A right triangle with hypotenuse is inscribed in , a circle with radius 26. If , evaluate the length of .

**Possible Answers:**

Insufficient information is given to answer the question.

**Correct answer:**

The arcs intercepted by a right angle are both semicircles, so hypotenuse shares its endpoints with two semicircles. This makes a diameter of the circle, and .

By the Pythagorean Theorem,
