Question

The length of the hypotenuse of a right triangle is 13 cm.if one of the side of the triangle be 5 cm long,find the length of the other.

Answer 1

13²-5²=AB²
AB=√144
AB=12
length of the other side is 12

Answer 2

H²=B²+P²
13²=5²+P²
P²=13²-5²
P²=169-25
P²=144
P=12
SO THE OTHER SIDE IS 12cm
