The answers to your question would be A. Housing B. medical expenses C. Groceries
Answer:

Step-by-step explanation:
Given:


Need:

First, let's look at the identities:
sum: 
difference: 
The question asks to find sin(A - B); therefore, we need to use the difference identity.
Based on the given information (value and quadrant), we can draw reference triangles to find the simplified values of A and B.
sin(A) = 
cos(A) = 
sin(B) = 
cos(B) = 
Plug these values into the difference identity formula.


Multiply.

Add.

This is your answer.
Hope this helps!
Answer: The tip is $17
Step-by-step explanation: You multiply $85 by .2 to get this answer.
They both equal 78 degrees because they are the same angle which means that they have the same degrees for f and e.
