Triangle ABC is a right triangle. The length of the legs are 3 in and 6 in, how long is the hypotenuse? (Round to the nearest tenth if necessary) A) 3.3 in
B) 6.7 in
C) 7.9 in
D) 9.0 in

Triangle ABC is a right triangle. The length of the legs are 3 in and 6 in, how long is the hypotenuse? (Round to the nearest tenth if necessary)

When the two legs are given, the hypotenuse is found by using the Pythagorean Theorem, which states that:

In the theorem, a and b are the two legs, and c is the hypotenuse. Since you are given the length of the two legs, substitute it into the equation.

Now, you need to square both 3 and 6. When you square a number, you're basically multiplying the number by itself.

Substitute the numbers into the equation.

Add:

You're looking for the value of c, not c squared. To remove the square, you need to square root it.

Using a calculator, find the square root of 45.

The answer to your question is B) 6.7 inches.

A

Step-by-step explanation:

Use Pythagorean Theorem in order to solve this:

(c is the hypotenuse)

So that would be:

If you solve this, you would find that:

Answer = B

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
