The first thing you should notice is that we need to see your work to see where you are getting stuck.
For #1, the first thing to do is draw the picture. The window is at some unknown height above the ground, and you need to draw two angles - one up to the bird and the other down to Emily. Once you have put all the numbers you know on the picture, you should use what you know about trig functions to continue.
#2 is again a picture with two right triangles, with Zane's eye the common vertex. Pick the numbers out of the problem - don't let the excess verbiage gets in the way.

We don't "give answers" - we check your work and give hints.Can you please give me the answers with drawing? I would really really appreciate that. I really don't know how to solve it because I have to teach myself, and solve these problems.
#1. start the plot by marking a point "Cassie's eye," or "C"
Draw a line upward at an angle of 53°. Mark a point on that line "Bird," or "B".
Drop a vertical line from the bird, and call the line "Rope"
Draw a line from Cassie's eye downward 27°
Where that line intersects the Rope, mark the point "Emiliy's feet," or "E"
What do you know about triangle CBE?
How can you find distance CB?
