Question

Find the length of the hypotenuse of a right triangle with legs of 9 cm and 12 cm

Answer 1

Use Pythagorean Theorem;
\[a ^{2}+b ^{2}=c ^{2}\]
So..
\[9^{2}+12^{2}=c ^{2}\]
\[9^{2}=9*9=81\]
\[12^{2}=12*12=144\]
Which means;
\[81+144=c ^{2}\]
\[225=c^{2}\]
\[\sqrt{225}=c\]
\[15=c\]
So, 15 is the hypotenuse.

Answer 2

81 + 144 =225. SQRT of 225 = 15 C=15
