Question

In a right triangle sides opposite to right angle is 5 cm. If one of the remaining two sides is of 4 cm then length of the third side is​

Answer 1

Step-by-step explanation:

[tex]Let the other side be x.

Then,

BY Pythagoras Theorem,

5square=4square + xsquare

25= 16 + x squre

x square = 9

x=3

Therefore,

We get the third side of the triangle is 3cm.



Answer 2

Answer:

3 cm

Step-by-step explanation:

let the third side be x

By Pythagoras theorem we know that

${5}^{2} = {4}^{2} + {x}^{2} \\ 25 = 16 + {x}^{2} \\ {x}^{2} = 9 \\ x = 3$
