Question

A right angle triangle has one of it sides to be 12cm and its hypotenusse is 13cm. what is the lenght of the other side?

Answer 1

Answer:

5 cm

Step-by-step explanation:

(hypotenuse)2=( one side)2 +( 2 nd side)2

hence

169-144= 25

taking square roots

we get above answer

Answer 2

Answer :-

The length of the other side of a right-triangle is 5cm.

Step-by-step explanation:

To Find:-

• The length of other side.

Let the length of other side of triangle be the base of triangle and 12cm be the perpendicular.

Given that,

• One side of right-triangle is 12cm
• The Hypotenuse of ∆ is 13cm.

We know,

• P² + B² = H²

Where,

→ P = Perpendicular

→ B = Base

→ H = Hypotenuse.

Therefore,

⇒ P² + B² = H²

⇒ 12² + B² = 13²

⇒ 144 + B² = 169

⇒ B² = 169 - 144

⇒ B² = 25

⇒ B² = 5 × 5

⇒ Base = 5cm

Hence, The other length of right-triangle is 5cm.
