In the figure, assume that *a* > 0. Prove that

To determine

**To prove:**

Explanation

It is given, *BD* = *a*, *DA* = 1, *BE* = *a* + 4 and *EC* = 3.

Find *BA* and *BC* using* BD* = *a*, DA = 1, *BE* = *a* + 4 and *EC* = 3.

*BA* = *BD* + *DA*

= *a* + 1

*BC*= *BE* + *EC*

= *a* + 4 + 3

= *a* + 7

Substitute *BD* = *a* and *BA* = *a* + 1 in

Substitute *BE* = *a *+ 4 and *BC* = *a* + 7 in
