What is the length of the hypotenuse
nika2105 [10]

<u>Given</u>:

Given that the length of the two legs of the right triangle are 28 m and 45 m.

We need to determine the length of the hypotenuse.

<u>Length of the hypotenuse:</u>

The length of the hypotenuse can be determined using the Pythagorean theorem.

Thus, we have;

hyp^2=28^2+45^2

Simplifying, we get;

hyp^2=784+2025

hyp^2=2809

Taking square root on both sides, we get;

hyp=\sqrt{2809}

hyp=53 \ m

Thus, the length of the hypotenuse is 53 m

Hence, Option C is the correct answer.

A set of numbers is said to be Pythagorean triple if the sum of the squares of the lesser numbers equal the square of the remaining number,

A. 28² + 45² = 2809    ;  53² = 2809     ; EQUAL
B. 16² + 63² = 4225    ;  65²= 4225      ; EQUAL
C. 13² + 84² = 7225    ;  85² = 7225     ; EQUAL
D. 11² + 61² = 3842    ;   62² = 3844     ; NOT EQUAL

The answer is letter D.
