Work shown above! Answer is
a = 5 b = -2 c = 0
Answer:
either of the 2 is read so the answer is 2/9
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!
-10/8 and + 15/8. Those should work.
Answer:
Step-by-step explanation:
2>-1
so solution is x>2
