Answer:
Step-by-step explanation:
we know that
Remember the identity
step 1
Find the value of
we have that
The angle alpha lie on the III Quadrant
so
The values of sine and cosine are negative
Find the value of sine
substitute
step 2
Find the value of
we have that
The angle beta lie on the IV Quadrant
so
The value of the cosine is positive and the value of the sine is negative
Find the value of cosine
substitute
step 3
Find cos (α + β)
we have
substitute
Do 5.4 plus 5.8 then do 3.4w minus 1.8w and whatever you get for each is your key to the expression. So if you were to solve the answers like A you would do 7(1.6+w) and see what you would get. Obviously A isn't the answer. Sorry, this is hard to explain. But the answer is C
