Question

two sides of triangle are 3 and 5 then find the length of third side?

​

Answer 1

Answer:

using Pythagoras theorem

5sq = 3sq +x

25-9= 16

root over 16 equal to 4

Answer 2

By Using Pythagoras Theorem ,

• let the third side be x

$\sf {(5)}^{2} = {(3)}^{2} + {(x)}^{2}$

$\sf {(x)}^{2} = 25 - 9 = 16 \implies x = \sqrt{16} = 4 \: cm$
