Question

What is the length of the hypotenuse of a right triangle if each of the two legs is 7 units? (1 point)

Group of answer choices

Square root of 14

7

Square root of 98

49

Answer 1

Square root of 98

Explanation:

The Pythagorean Theorem states that a^2+b^2=c^2.

This means that the sides are represented by a^2+b^2. In order to find the hypotenuse in this problem, we substitute a and b for 7 and 7.

7^2+7^2=c^2

we do what it shows us and get:

49+49=c^2

from there, we add the left side altogether then square each side to get rid of the root.

98=c^2

√98=√c^2

and since 98 can't have two numbers that multiply together and be the same number, we leave it as is like this:

√98 = c
