X=16 PLZ HELP
Answered by bobpursley
nope.
it is a right triangle;
x^2+5^2=13^2
x^2=169-25
x^2=144
solve for x
Answered by Ms. Sue
No. I don't know how you got 16.

Please use the Pythagoras Equation that Reiny posted.

We've checked two of your guesses. Do not post this problem again.

You have rudely ignored both Bobpursley's and Reiny's and my responses. You don't need to post here if you are going to ignore the tutors' advice. Be careful; you're on the verge of being banned.
