Which is the length of the hypotenuse of the triangle?

Pepsi [2]

Since this is a right triangle, we can use the Pythagorean Theorem, which states a² + b² = c² in a right triangle.

Plugging our numbers in, we get:

(12)² + (35)² = c²

From there, we can square the numbers.

(144) + (1225) = c²

Then, we can add them together to find the sum;

(1369) = c²

And finally, we can find the square root of both sides.

(37) = c

Therefore, 37 is the answer and your answer choice is correct.
