Answer:39+8r

Step-by-step explanation:

To find the answer you have to distribute the problem. To do this you do (4×5) and (4×8r). Whenever you do this you get 20+8r+19. You then need to add common factors in which for this problem would be 20 and 19. Whenever you add 20+19 you get 39 and then since the 8 has a r on the side you don't do anything with it so you just put 39+8r and that would be your answer

Answer:

x = 12.489996 ft

Step-by-step explanation:

In order to solve one side length of a right triangle given two of other side lengths, you can use the pythagorean theory.

The theory states that the sum of the two adjacent side squares equals the square of the hypotenuse.

Basically:

$x^2 + y^2 = h^2$

Since the problem gives you the hypotenuse and one adjacent side length you rearrange the formula as so:

$x^2 = h^2 - y^2$

$x=\sqrt{h^2 - y^2}$

Then plug in the values:

$x = \sqrt{16^2 - 10^2} = \sqrt{256-100}=\sqrt{156} = 2\sqrt{39}=12.489996$
