2. A cell tower is 20 feet tall. A right triangle is formed with the endpoints: top of the tower, bottom of the tower, and the point where the cell signal hits the ground at a 50-degree angle. Use a trig table to find the particular trig function value you need to answer the following questions. Round your answers to two decimal places. a. What is the length of the signal? b. When the signal hits the ground, how far is it from the base of the building? 4. Does (sin?(x)/cos(x)) - sec(x) = cos (x) ? PROVE IT! Use a simplification table to prove it. Add lines to the table as needed. Expression Rationale (sin?(x)/cos(x)) - sec(x) Original Expression
