Lol, bro, 15.68 is your solution
Answer: Is D
Step-by-step explanation:
I hope I am right if I'm not please correct me
Given that C is the midpoint of AB so from this result that AC = BC so given that AC = 20 => BC = 20 too
and given that AB = 5x so AB = AC +BC so AB = 20+20 so AB = 40
than AB = 40 and AB = 5x so result 5x = 40 => x = 40/5 so x = 8
hope this will help you
