1.) From a point on the South Rim of a canyon, it is found that the angle of elevation to a point on the North Rim is 2.1 degrees. If the horizontal distance between the points is 8.3mi, how much higher is the point on the North Rim?

The point on the North Rim is nothing ? miles higher than the point on the South Rim.

2.) How tall is a building that casts a 70-ft shadow when the angle of elevation of the sun is 33 degrees?

3.)The angle of inclination of a road is often expressed as a percent grade, which is the vertical rise divided by the horizontal run (expressed as a percent). A 9.0% grade corresponds to a road that rises 9.0ft for every 100 ft along the horizontal. Find the angle of inclination that corresponds to a 9.0% grade.

4.)Find theta for 0 degrees less than or equals theta less than 360 degrees.

sin theta

equals -0.8244

5.)Determine the function that satisfies the following conditions.

Find sine theta when cosine theta equals 0.548 and tangent theta less than 0.
