Question 844938
the only way i could solve this was through the use of the law of sines.
the attached diagram shows you the situation.

i had to assume she was walking from west to east.
otherwise the church would not have been able to be located.
i translated N48E and N67W based on the information supplied in the following link:

RT4DP means rounded to 4 decimal places.
i'm assuming this is a trigonometry problem.
i couldn't figure out  how to solve it without using trigonometry.
i did verify that the answer is correct by using the law of cosines to solve for the distance after all sides were measured using the law of sines.  
The law of cosines confirmed that the length of line segment b was done correctly.
