<h2><u>
x = 8.2</u></h2>
Step-by-step explanation:
A^2+B^2=C^2 is the pythagorean theorem to find a missing siede of a triangle.
First triangle on the right:
5^2+B^2=10^2
25+B^2=100
B^2=75
B=8.66025404
B=8.7
Second triangle of left:
3^2+B^2=8.7^2
9+B^2=75.69
B^2=66.69
B= 8.16639455
B=8.2
x=8.2

Answer:
<h2>17</h2>
Step-by-step explanation:
f(x) = 11 - 3x
f(-2) - <em>put x = -2 to the f(x):</em>
<em />
f(-2) = 11 - 3(-2) = 11 + 6 = 17
