Abeam rests against a wall, forming a 65 degree with the floor. use the function y=9sec theta to find the length of the beam to the nearest tenth of a foot. a. 8.2 ft b. 21.3 ft c. 9.9 ft d. 18.7 f

B. 21.3 ft.

Step-by-step explanation:

We have been given that a beam rests against a wall, forming a 65 degree with the floor. We are asked to find the length of the beam using function

Upon substituting the value of theta 65 degrees in our given equation we will get,

Therefore, the length of the beam is 21.3 ft and option B is the correct choice.
