Answer: h=5.66ft

Step-by-step explanation:

Observe the picture attached.

Find the value of "x" and "y" using the Pythagoren Theorem:

a^2=b^2+c^2

If you solve for "a":

a= \sqrt{b^2+c^2}

Where "a" is the hypotenuse and "b" and "c" are the legs.

In this case, for "x" you know that:

a=x\\b=8ft\\c=2ft

Then, the value of "x" is:

x=\sqrt{(8ft)^2+(2ft)^2}\\\\x=8.24ft

For "y" you can see that:

a=10ft\\b=8.24ft\\c=h

Subsituting values and solving for h, you get:

(10ft)^2=(8.24ft)^2+h^2\\\\h=\sqrt{(10ft)^2-(8.24ft)^2} \\\\h=5.66ft

It would be y=4x-3 because -11 show that it went down 11 units. So if it is going to go up 8 units, -11+8 is -3.
