Question

Find the third side of a right angled triangle whose hypotenuse is 13cm and one side is 5cm

Answer 1

Hey mate this is your answer

Let the other side be x

So, according to pythagoras theorem

(5)²+(x)²=(13)²

25+x²=169

x²=144

x=√144

x=12

So, the other side is 12

Answer 2

Answer:

Third side=12cm

Step-by-step explanation:

Given:

Hypotenuse = 13cm

Base = xcm(It is not given)

Height = 5cm

Using RHS:

$AB^{2}=AC^{2}+BC^{2}$

$13^{2}=5^{2}+x^{2}$

$169=25+x^{2}$

$169-25=x^{2}$

$144=x^{2}$

$\sqrt{144}=x$

∴$x=12$ (third side)
