Answer 2

Answer:

The length of AB is 19.

Step-by-step explanation:

Lengths BC and AD are congruent to each other.

BC: 17x + 4 equals AD:18x

17x + 4 = 18x .... that's the equation it makes and the equation we are going to solve.

$\ 17x + 4 = 18x \\ \frac{ - 17x \: \: \: \: \: \: \:\: = - 17x} {4 = 1x} \\ \\ \frac{4 }{1} = \frac{1x}{1} \\ 4 = x$

Since we found out the value for 'x', now we are going to plug it in 4x + 3.

$4x + 3 \\ 4(4) + 3 \\ 16 + 3 \\ 19$

The length of AB is 19.
