Step-by-step explanation:
The lines parallel to one another are equal to one another. The angles have it similar, but the opposite are equal to each other and the consecutive angles are equal to 180. You take the given angle and subtract by 180.

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!
