Question
1. To determine the height of a tree, a person stands 40 feet from the tree and finds that the angle of elevation at that point is 37 degrees. Find the height of the tree, to the nearest whole number. 2. Give the reference angle for an angle of measure 1013°. 3. Give the reference angle for an angle of measure 2T radians. 4. Graph one period of y = -2 sin 3 (x -) + 1. Include a discussion of amplitude, period, horizontal and vertical shifts, and midline. Give coordinates of the starting and ending points of your graph, as well as the points 1/4, 1/2, and 3/4 of the way through the period.
