trigonometry
Hal walked from point A to point B due north east from a distance of 20m. He immediately changed direction and walked 50m from B to C on a bearing of 110 degrees. 1. calculate the distance AC 2. Find the bearing of C from A

trigonometry
two pieces of wire stretched from the top, M of a vertical pole to the points L and N on the horizontal ground. the angle of depression of L from N =65 degrees. N is on the opposite side of the pole(from left)at an angle of depression of 72 degrees from M. Find the length of e...

trigonometry
Find all the angles between 0 degrees and 360 degrees which satisfy the equations a. 8 cos x sin x = sin x b. 5 tan^2 y + 5 tan y = 2 sec^2 y.

trigonometry
state the amplitude, period and phase shift of the function y = tan (2 theta- 180 degrees)

trigonometry
The function should read y = tan(2 theta - 180 degrees).

trigonometry
state the amplitude, period and phase shift of the function y=tan (20-80 degrees)

trigonometry
express 3 cos x -2 sin x in th eform R cos (x + a) and hence write down the maximum and minimum values of 3 cos x - 2 sin x.
