answer the question
What is the third side​

Answer 1

Answer:

By Pythagoras theorum

${48}^{2} + {48}^{2} = {cb}^{2} \\ 2304 + 2304 = {cb}^{2} \\ 4608 = {cb}^{2} \\ \sqrt{4608} = cb \\ 67.88 = cb$

Answer 2

Answer:

The third side is 67.9cm.

Step-by-step explanation:

The given triangle is a right angled triangle.

We can find the 3rd side by using Pythagoras theorem i.e.,

BC²=AB²+AC²

Here, AB=AC=48cm

substituting the values

BC²=48²+48²

⇒BC²=2*2304

⇒BC=√4608

⇒BC=67.9cm.
