Question

The legs of a right triangle are 5m and 12m long. What is the length of the hypotenuse? Explain how you found your answer.

Answer 1

by using pythagoras theorem
\[c^2=a^2+b^2\]where c is hypotenuse
\[c^2=(5)^2+(12)^2\]
\[c^2=25+144\]
\[c^2=169\]
\[c=\sqrt{169}\]
\[c=13\]
so, hypotenuse=13
