Hi again 
Just tried posting in Homework help but I didn't have administrative privileges apparently so i might post here.
I am in desperate need of help with Yr 11 Three Dimensional Trig.
Drawing a diagram and interpreting wording problems is my biggest struggle.
If anyone can be so helpful and kind to show me I'd much appreciate it and find some way to repay him/her
1. A straight stick 2m long is stuck in the ground and is inclined at 60 degrees to the horizontal pointing at an easterly direction. Calculate the length and directing of the shadow of the stick when the sun is due north at an elevation of 30degrees.
2.Two groups of people set off to spotlight possums at night.
One group spots a possum. The tree that has the possum is at a bearing of North 28degrees West. The angle of elevation of their spotlight is 38degrees. At this instant the other group, which is 100m West of the first group, sights the same tree at a bearing of N29E. How High up is the possum?
Thanks so much if you can help and explain :laugh:
