Answer:
-12
Step-by-step explanation:
(-17)- (3)+ (-2)= answer
go from left to right
The expression on the left simplifies to
tan(x) - sin(x)/cos(x) = 0
So, your expression is 0 = cos(x). This matches your answer choices ...
c. cos(x) = 0_____
Of course, at cos(x)=0, the entire left side of the equation amounts to 1/0 - 1/0, so is undefined. Effectively, there is no solution.
