# Given right triangle ABC, with right angle at C, if b = 8 and c = 17, using the Pythagorean Theorem, what is a?

A is 15.

So let write the Pythagorean Theorem equation out.

So our value of b is 8 and c is 17. So let plug those number into the equation.

Now you square the known value which you will get:

Subtract 64 from both sides and you get:

Square both side:

So the final answer is a = 15

So let double check to ensure that it adds up to 289. If it does not, then somewhere along the way I made a math calculation error.

So a = 15 work.

Using the Pythagorean Theorem, (a) can be calculated as (a = \sqrt{c^2 - b^2}). Plugging in the given values, (a = \sqrt{17^2 - 8^2} = \sqrt{289 - 64} = \sqrt{225} = 15). Therefore, (a = 15).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
