Question

In triangle ABC, angle c is right angle 'a' and 'b' are the legs and c is the hypotenuse. find where a=12, b=9.

Answer 1

By Pythagoras theorem it is 15

Answer 2

In Triangle ABC,
By hypotenuse theorem ,
(h) square= (p) square + (b) square
(c)square=(a)square+(b)square
(c)square= (12)square+(9)square
(c)square=144+81
(c)square =225
(c) = √225
c=15
