To determine the hypotenuse, use the formula a^2 + b^2 = c^2.

Place 80 as "a" and 39 as "b". Your formula should look like 80^2 + 39^2 = c^2.

Next, plug this into your calculator to get 7921. Then square root 7921.

7x - 4 + 4 = -182 + 4

Simplify

7x = -178

Divide both sides by 7

7x/7 = -178/7

Simplify

x = -178/7

Decimal form = -25.4285714286
