Answer:

7. No. 8. Yes.

Explanation:

Use the pythagorean theorem.


a^(2) + b^2 = c^2

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

7.


3^2 + 7^2 \\eq √(57)^2 \\9 + 49 = 58 \\eq 57

So it isn't a right triangle.

8.


(5√(5))^2 = 11^2 + 2^2\\(√(125))^2 = 121 + 4\\125 = 125

So this is a right triangle.
