Question

AB=15; AD=36. What is the value of AC+BD

Answer 1

AC+BD = 78

Explanation:

Given that,

AB = 15, AD = 36

We need to find the value of AC+BD.

`BD^2=AB^2+AD^2`

We can find BD.

`BD^2=15^2+36^2\\\\BD=39`

According to figure,

BC should be equal to AD and AB should be equal to CD.

AC+BD = BD+BD

= 2BD

= 2 × 39

= 78

So, the value of AC+BD is equal to 78.
