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.
