Find the unknown side length, x. write your answer in simplest radical form.

a. 15
b. 11√2
c. 2√121
d. 15√5

  B. 11√2

Step-by-step explanation:

x is the length of the hypotenuse of an isosceles right triangle with leg length 11. Its measure is x = 11√2.

__

Consider a right triangle with legs (a and b) of length 1. Then the Pythagorean theorem tells you the hypotenuse (c) has length ...

  c = √(a²+b²) = √(1²+1²) = √2

This same ratio of leg lengths to hypotenuse length (1 : 1 : √2) applies to all isosceles right triangles. So, the length of the hypotenuse is always √2 times the length of a leg in such a triangle.
