Question

What is the length of the hypotenuse in this right angle?

A. 5 inches

B. 11 inches

C. 13 inches

D. 34 inches

Answer 1

C. 13 inches

Explanation:

Use the Pythagorean Theorum which is a^2+b^2=c^2. You only know a and b so plug them in. 5^2+12^2=c^2. Simplify to 25+144=c^2. Simplify again to get 169=c^2. Find the square root of 169, which is 13 and there is your answer.

Answer 2

C. 13 inches

Explanation:

using pythagorean theorem

a^2 + b^2 =c^2 where a and b are the legs and c is the hypotenuse

5^2 + 12^2 = c^2

25+144 =c^2

169 = c^2

take the square root of each side

sqrt(169) = sqrt(c^2)

13 = c
