The answer is a. 12.21

Because a^2+b^2=c^2
This would be leg^2+leg^2=hypotenuse^2

7^2+10^2=c^2
49+100=c^2
149=c^2
Cancel the square root by squaring 149 and that should equal about 12.21

Answer:

A. 12.21

Step-by-step explanation:

Define and explain:

This a right triangle, so the Pythagorean Theorem applies. The Pythagorean Theorem states that the sum of the squared legs is equal to the squared hypotenuse.

The legs of a triangle are the sides that form the right angle.

The hypotenuse is the longest side.

Formula:

[tex]a^2+b^2=c^2[/tex]

[tex]a,b-legs[/tex]

[tex]c-legs[/tex]

Here, I am solving for the hypotenuse.

[tex]7^2+10^2=c^2[/tex]

[tex]49+100=c^2[/tex]

[tex]149=c^2[/tex]

The last step is to find the square root of 149.

The square root of 149 is irrational, of course, so I must round the square root to the nearest hundredth.

[tex]12.2065556157[/tex] ≈ [tex]12.21.[/tex]

[tex]12.21=c[/tex]

Conclude:

I, therefore, believe the length of the hypotenuse is 12.21.
