Asked by Missy K.

The length of the hypotenuse of a rigth triangle with sides of 6mm and 8mm?
Answered by Ms. Sue
The sides are a and b. The hypotenuse is c. Use the Pythagorean Theorem.

a^2 + b^2 = c^2

I'll be glad to check your answer.

100 is my answer
Answered by Ms. Sue
That's only one step of the problem. But 100 isn't a reasonable length.

You forgot to take the square root of 100.

Answered by Missy K.
so the answer is 10?
Answered by Ms. Sue
Yes. The hypotenuse is 10 mm long.
