Answer 1

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:

$a^2+b^2=c^2$

$a,b-legs$

$c-legs$

Here, I am solving for the hypotenuse.

$7^2+10^2=c^2$

$49+100=c^2$

$149=c^2$

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.

$12.2065556157$ ≈ $12.21.$

$12.21=c$

Conclude:

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

Answer 2

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
