## Elementary Geometry for College Students (5th Edition)

Given that triangle is right angle triangle where a=12 and b=5 and c has to be found formula for finding hypoteneus of right andle triangle is $a^{2}$+$b^{2}$=$c^{2}$ so after putting values of a and b, $12^{2}$+$5^{2}$=$c^{2}$ 144+25=$c^{2}$ $c^{2}$=169 $\sqrt c$=13
