Find the missing length.

To find the missing length of this triangle you need to use the Pythagorean Theorem.

As shown in the image we are given three sides: 1, 8 and c and so you have to substitute these numbers into the equation a squared + b squared = c squared.

So it should look like:

1 squared + 8 squared = c squared, so solve it to be

1 + 64 = c squared which is 65 = c squared

Now you have to isolate the variable c because that is what you are trying to find so you must square root both sides:

\sqrt{65} = c

So that should be your answer.

Hope this helps!

(if it doesn't work then you might have to simplify)
