Question

What is the length of the hypotenuse of a right triangle whose legs have lengths of 5 and 12?

a)13
b)15
c)17

Answer 1

In the triangle above, you are given measures for legs a and b: 5 and 12, respectively. You can use the Pythagorean Theorem to find a value for the length of c, the hypotenuse. Using the formula, you find that the length of c, the hypotenuse, is 13.

Answer 2

Tha answer is A.

Explanation:

Given that hypotenuse of a triangle is the longest length so you have to apply Pythagoras Theorem :

hypo² = side² + side²

hypo² = 5² + 12²

hypo² = 25 + 144

hypo² = 169

hypo = √169

hypo = 13 units
