asked • 02/20/23A guy wire 1832 feet long is attached to the top of a tower. When pulled taut, it touches level ground 843 feet from the base of the tower. What angle does the wire make with the ground? Express your answer using degree measure rounded to one decimal place.
Create a diagram to show that the leg of the right triangle measuring 843' is adjacent to the requested angle, and the hypotenuse measures 1,832'.
As always, we use inverse trigonometry to calculate an angle measure. Thus, if we name the requested angle Θ, we have cosΘ = 843/1832 and Θ = cos-1(843/1832).
