No homework will be graded that has not been received and processed by Bb by the deadline. 1. For the triangle below, the height is 10 feet and the base is 10 /3 feet. Calculate the following values using trig ratios. a. Hypotenuse = b. sin () = e. csc (0) = c. cos (@) = f. sec (0) = d. tan ) = g. cot (0) = 2. Prove that tan x* sin x = sec X - COS X 3. a. A shed's roof is 10 foot above ground level. A security lamp is on the ground shining up at the roof. The angle of elevation of the light beam is 60 degrees. (i.e. the light beam hits the shed roof at a 30 degree angle.) Use a trig function to calculate the length of the light beam. b. Use a trig function to calculate the distance of the lamp from the base of the shed. 1 s3.us-east-1.amazonaws.com 6 + https://s3.us-east-1.amazonaws.com/blackboard.learn.xythos.prod/5a30bcf95ea52/14495964?response-content-disposition=inline%3B%20filename%2A%3DUTF-8%27%271T102%2520Chapter%252012%2520Homework%2520Spring%...
