An office worker is looking out a window W from the top floor of a building standing on level ground. From W, a car C has an angle of depression 2a, while a balloon B directly above the car has an angle of elevation a. The height of the balloon above the car is x, and the height of the window above the ground is h. How do you show that tan 2a/h = tan a/x-h?

i think c. but don't trust it.

step-by-step explanation:

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

well the answer to that is xoxoxo
