Answer:

x= 3.25

Step-by-step explanation:

4x-5=8

1. Take the -5 to the other side as a plus so now your question is

4x=13

2. to get the x by its self divide both sides by 4.

13 divided by 4 is 3.25

therefore x=3.25

Use the Pythagorean theorem:

$x^2+8^2=17^2\\\\x^2+64=289\qquad\text{subtract 64 from both sides}\\\\x^2=225\to x=\sqrt{225}\\\\\boxed{x=15\ ft}$
