A right triangle is shown below.

Norma-Jean [14]

<h2>Answer: <em>x = 7.5</em></h2>

<em />

Step-by-step explanation:

Use the Pythagorean Theorem ( $a^{2}+b^{2} =c^{2}$ )

The longest side is <em>c = the hypotenuse</em>, and <em>a and b = the other sides</em> of the triangle.

a = 4 First: $4^{2}+x^{2}=8.5^{2}$

b = x Second: $16+x^{2}=72.25$

c = 8.5 Third: $x^{2}=56.25$

Fourth: $x=\sqrt{56.25}$

Fifth: x = 7.5
