Question

What is measure of side c in the triangle below

Answer 1

By the Pythagorean theorem:

$c= \sqrt{5^2+12^2}= \sqrt{25+144}= \sqrt{169} =13$


B. 

Answer 2

B. Since it is the hypotenuse it has to be solved with a(squared)+b(squared)=c(squared) so:        25+144=c(squared)      then 169=c(squared)   so square 169 and you answer is: 13=c so the answer is 13
