## 3D

Hey guys,

I am here with some more trig problems.

Can you please help me with these 3D trig questions?

The first one with the tower is killing me. I tried that a number of times, however I seem to be getting 89m (nearest metre) as the answer. However, the answer is 84m. Could you please help if you are able to get the correct answer to this.

The next two questions, I have difficulty imagining the 3D aspect to it.

Your help would be greatly appreciated!
