Question

I think that the answer is b can you please help me out ?

Answer 1

The definition of tan(F) is opposite (40), divided by adjacent (9), so the answer is tan(F) = 40/9.  Therefore, your answer is C.

Answer 2

Answer:
tan F = 40/9 which is the third option

Explanation:
Triangle DEF is a right-angled triangle. This means that we can apply the special trigonometric function.
This means that:
tan θ = opposite / adjacent
In the given:
θ = F
opposite is DE = 40
adjacent is DF = 9
Substitute in the above equation:
tan F = 40/9

Hope this helps :)
