Please help me with trigonometry

https://i.imgur.com/aLAIl5k.png

You have climbed to the top of a tall tree. When you get to the top, you use your clinometer to discover that the angle between the tree and the line of sight to your red lunchbox is 30°. You know you left the lunchbox 20 meters from the base of the tree. How tall is the tree?

A. 75.36 m
B. 92.09 m
C. 20.17 m
D. 51.25 m
E. 18.95 m
F. 34.64 m

The last question!! Please help, I'd love to get this done as quickly as I can. Thank you!!
