Hope this helped, Have a Wonderful Day!!
There's not much you can or should do here other than to "solve for d."
Subtract 22 from both sides. Then 22 - 22 - 28d = -12 - 22 = -34
Then -28d = -34, and d = -28 / (-34) = + 14/17 (answer)

Answer:
4√3.
Step-by-step explanation:
If the height is h then
tan 60 = h / (1/2*8)
tan 60 = h/4
h = 4 tan 60
= 4 * √3.
