Answer:
x = √53
Use the pythagorean theorem to solve for x, which would be c in the equation a^2 + b^2 = c^2.
(a and b are the sides that meet up in a right triangle, c is the hypotenuse. In this case, you are solving for the hypotenuse.)
Step-by-step explanation:
1. Plug in the numbers in the pythagorean theorem.
2^2 + 7^2 = c^2 (remember, each variable is squared)
2. Simplify.
4 + 49 = 53
Since each variable in the pythagorean theorem is squared, the side value would be √53.
