Question

15) The hypotenuse of a right triangle is 13cm long. If one of the remaining two sides is of length 5 cm, find the length of another side.
need step by step ​

Answer 1

Given that,

Hypotenuse=13cm

Length(perpendicular)=5cm

Another side=?

Let the another side=Base

So,

By Pythagoras theorem,

=144

B=12

Hence, the another side=12cm.

Answer 2

Step-by-step explanation:

Let AB = 5cm, BC = ? & AC = 13cm

From Pythagoras theorem,

AC²=AB²+BC²

(13)²=(5)²+BC²

169=25+BC²

144=BC²

BC=√144

BC=12cm
