Answer:
13
Step-by-step explanation:
Is there more info to this problem? I'm assuming both triangles are congruent. If so then you can assume that BC = CD
If that's the case then set them equal to each other to solve for x then plug x back into the side for CD to get the value
6x-5 = 4x+1
2x = 6
x = 3
Plug into CD 4(3) +1
= 13
THIS IS ASSUMING TRIANGLE ABC = ADC
