Suppose you know that tan squared open parentheses theta close parentheses equals 24. Determine one of the values of s e c open parentheses theta close parentheses.

Please help thank you!

The question is x^2+y^2=36 x^2-6y=36 Thanks

I tried to do it but I keep getting wrong answers ∠A=50 degrees, ∠B=75 degrees, a=20. Find side b

I'm not sure how to do it csc theta = -3 and cos>0 Find the remaining 5 trig values

x^2-y^2=3 2x+y2=5 I'm stuck at a part where it becomes x^2+2x+2 and I can't factor it. Help would be appreciated

I can't seem to solve this 8^x=72

I'm having trouble understanding the question. The question is Sec theta=-4, sin theta<0, find the remaining functions.

If 0≤x≤90 and tan x=15/8, then cos x=?

I'm assuming these angles are from North. Also tried drawing it but i still cant get the answer.

How do I solve this question?

I tried solving it but the calculator gave me a error and I would like help to see what I did wrong. First i did the formula I used a^2=b^2+c^2-2BCCosA 50^2=10^2+20^2-(10)(20)CosA 2500=100+400-400CosA 2500=500-400CosA subtracted...

I can't seem to do this and i appreciate the help
