there are a couple of steps to this question. 

1. find the length of the hypotenuse labels a 

2. next find the angle x

3. lastly use the law of sin to find the distance between the zoo and library

the alternate method is to find the length of the base in each right triangle

find x and y using the tan ratios. 

the the distance between the zoo and library is y - x
