Question

Which expression gives the length of JK in the triangle shown below?

Answer 1

Answer:

d

Step-by-step explanation:

by using the a²+b²=c²

c²=

$\sqrt{24 { }^{2} } + 31 {?}^{2}$

Answer 2

Answer: Choice D

Explanation:

We use the pythagorean theorem to form that expression since $a^2+b^2 = c^2$ can be solved to $c = \sqrt{a^2+b^2}$, then we plug in a = 24 and b = 31.

The side JK is the hypotenuse, which is always opposite the 90 degree angle and it's always the longest side.
