Answer:
AC+BD = 78
Step-by-step explanation:
Given that,
AB = 15, AD = 36
We need to find the value of AC+BD.
[tex]BD^2=AB^2+AD^2[/tex]
We can find BD.
[tex]BD^2=15^2+36^2\\\\BD=39[/tex]
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.
