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.

ha!

i just did this!

18. g

20. h 30 degree turn.

21. d 90 degree angles

and also 19 is a. a sphere not a cirlcle

hope i !

pls mark me brainiest

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing
