(x + 1) / 5 = (x + 5) / 7
cross multiply
(x +1) x 7 = 5 x (x + 5)
7x + 7 = 5x + 25
take the like terms to one side
7x - 5x = 25 - 7
2x = 18
divide by 2 to isolate x
2x / 2 = 18 / 2
x = 9
check:
9 + 1 / 5 = 9 + 5 / 7
10 / 5 = 14 / 7
2 = 2

Answer:
CD = 3.602019190339
Step-by-step explanation:
CD = DA - CA
DA = DB×Cos(29) = 18.7×cos(29) = 16.355388523507
BA = BA×cos(43) = 18.7×cos(43) = 13.676314220278
CA = BA÷tan(47) = 13.676314220278÷tan(47) = 12.753369333168
Then
CD = 16.355388523507 - 12.753369333168 = 3.602019190339
