I got it, thank you so much!
In the diagram, tanC = 2.4. Find cos A.
C

A____________B
(Pretend there's a line from A to C, and angle ABC is a right angle)
Right now, what I have is:
tan(C)=AB/BC=2.4
cos(A)=AB/AC
Could I have a hint as to how to solve this, please? Thanks in advance!
I got it, thank you so much!
Thank you for the help!
For the first one, I managed to solve for what AD is, but I'm stuck on getting the value of AE. I was thinking maybe I could use similar triangles (pretend the point at which DC and AE intersect is called O) DOE and AOC to solve for side AE, but I've been trying and I haven't been able to do that. Could you help?
For the second one, I got , is that right? I found the circumference of the middle of the sphere to be just pi, and 1/4 of that is 1/4pi, and then you multiply that by 3.
Thanks in advance!
