Given : BD is a median

AD = 7x + 5

DC = 9x - 5​

________________

AD + DC= AC

Since BD is a median, D is a middle point

AD = DC

7x +5 = 9x -5

9x -7x = 5 +5

(9-7) x= 10

x= 10/2

x= 5

______________

AD = 7x +5

= 7*5 + 5

= 40

____________

DC = 9x -5

= 45- 5

= 40

_____________

AD + DC= AC

AC= 40 + 40

AC = 80

__________________________

Answer

x= 5

AD= 40

DC= 40

AC= 80
