Sagot :

nomin7

Answer:

d

Step-by-step explanation:

by using the a²+b²=c²

c²=

[tex] \sqrt{24 { }^{2} } + 31 {?}^{2} [/tex]

Answer: Choice D

Explanation:

We use the pythagorean theorem to form that expression since [tex]a^2+b^2 = c^2\\\\[/tex] can be solved to [tex]c = \sqrt{a^2+b^2}\\\\[/tex], 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.
