Question

A right angled triangle has one of its sides to be 12cm and its hypotenuse 13cm .what is the length of the third side?.

Answer 1

Answer:

Since it is a right angle triangle .we use PYTHAGOREAS THEOREM for finding third side

Hypotenuse)²=( 2nd side )² + (3rd side)²

(13)² = ( 12)² + (x)²

169 = 144 + (x)²

(x)² = 169 -144

(x)² = 25

x = 5 ( Third side)

Answer 2

In this question, There is a right triangle given. And we have to find its one side , let it be base or perpendicular. -> By using pythagoras theorem, -> H^2 = P^2 + B^2 -> (13)^2 = (12)^2 + B^2 -> 169 = 144 + B^2 -> B^2 = 169 - 144 -> B^2 = 25. -> B = 5cm... thats your answer,...
