Answer:
option A is the correct choice
Step-by-step explanation:
The trigonometric equation you are using has a general form
y = A* tan w*(x - r)
Where
A is the amplitude of the function
w is the frequency rad/s
r is the phase shift
In your case
A = 2
B = w = 3
r = pi/2
y = 2* tan 3*(x - pi/2)
9.9
use the special triangle formula or use cosine to find BC
Answer

just use ur calculator since my teacher let us use the calculator i just typed in 16.(-4) and got -64
it means poop
