Answer:
The answer to your question is CB = 55
Step-by-step explanation:
AC = 7x + 11
AB = 2x + 29
CB = 4x + 3 = ?
We know that AB = BC, then
2x + 29 = 4x + 3
2x - 4x = 3 - 29
- 2x = - 26
x = -26 / -2
x = 13
Find the value of CB
CB = 4x + 3 = 4(13) + 3 = 52 + 3 = 55
AB = 2x + 29 = 2(13) + 29 = 26 + 29 = 55
