Question

If the lengths of the legs in a right triangle are 7 and 8, what is the approximate length of the hypotenuse?

Answer 1

a^2+b^2=c^2

Answer 2

Use the formula @audreynicole47 gave you.

Pythagorean Theorem!

The legs are either a or b (it doesn't which is which) and the hypotenuse is c.

So, just plug your numbers in and simplify!

To set it up:
7^2 + 8^2 = c^2

Solve for c.

Answer 3

113?

Answer 4

Yes. That is c^2. Then you square both sides and solve.

Answer 5

Now just take the square root of that number because c^2=113, so c + ??

Answer 6

It should be about 10.6
