Using the Pythagorean Theorem, find the length of a leg of a right triangle if the other leg is 8 feet long and the hypotenuse i

iren [92.7K]

The Pythagorean Theorem tells us that $a^{2}+b^{2}=c^{2}$ where c is the hypotenuse and a and b are the other two sides. To solve for one of the shorter sides we need to rearrange:

$b=\sqrt{c^{2}-a^{2}}$

We can then substitute known values, and solve:
 $b=\sqrt{10^{2}-8^{2}}$
$b=\sqrt{100-64}$
$b=\sqrt{36}$
$b=6 feet$

Isaiah spent:

3 (x - 2.25)

2x = 3x - 6.75
3x - 2x = 6.75
x = 6.75
