Question

Find the length of the other side of a right angled triangle if one side is 12 cm and the hypotenuse is 13 cm

Answer 1

Answer:

Hypotenuse ^=base^ +height ^

13^=12^+h^

169=144+h^

25=h^

5cm is the other side

Answer 2

Answer:

5 cm.

Step-by-step explanation:

Given :

ABC is right angled triangle in which AB = 12 cm and AC = 13 cm.

We have to find BC.

We have pythagoras theorem

$\large ( hypotenuse)^2=(perpendicular)^2+(base)^2$

Here values are

$\large ( AC)^2=(AB)^2+(BC)^2\\\\\\\large \text{Rewrite as }\\\\\\\large (BC)^2=( AC)^2-(AB)^2\\\\\\\large (BC)^2=( 13)^2-(12)^2\\\\\\\large (BC)^2=169-144\\\\\\\large (BC)^2=25\\\\\\\large (BC)=\sqrt{25}\\\\\\\large (BC)=5$

So length of the other side of a right angled triangle is 5 cm.
