Question 802600: I could use a little help with this math question for my ACT prep worksheets I've been working on. It is question 433 in my booklet:
Using a right triangle with an acute angle theta, find the other five trigonometric functions of theta if cos theta = 2/5 I am told not to use decimals in my answer.
I was hoping you could show me the answer and sort of a guide/process of how you got it, so I can be sure to really learn from it and make sure I "get it down" for future similar questions. Thank you for taking the time to answer my question, Reggie

Question 1004151: you are standing at the top of a 500m tall building. across the street is a shorter building. at ground level, the two buildings are 50 meters apart, and if you measure the angle of depression from the top of your building to the nearest edge of the shorter building, you get an angle of pi/6. how tall is the other building?
a) 500 - 50 sqrt 2 meters
b) 500 - 50/sqrt 2 meters
c) 500 - 25/sqrt 2 meters
d) 500-50/sqrt 3 meters
e) 500 - 25 sqrt 2 meters
f) 500 - 50 sqrt 3 meters

Question 890524: My question was log of sqrt (x (sqrt (2y (sqrt (z))))
What I did was (1/2)logx sqrt (2y (sqrt (z))
(1/2)logx(1/4)logy^2 sqrt (z)
(1/2)logx(1/4)logy^2(1/8)logz
Then factored that to (1/2)[logx(1/2)logy^2(1/4)logz]
But my professor counted it as wrong and I hope it's not too confusing the way that I typed it but the formula system wouldn't work for me. I just wanted to see where I went wrong with this question. Thank you!

Question 1114896: Given: cos (-105)
Find the exact value of the function without the use of a calculator.
I was unsure what to do with a negative, but from examples, I did the following where it "ignores" the negative.
cos (105) = cos (135 - 30)
Final Answer: 
If the final answer is right, why does the (-) go away and if that procedure is incorrect how would you split up the -105? Thank you for any help!
