Abillboard is supported by 20-foot lengths of tubing at an angle of 60°. how far from the base of the billboard is the bottom end of the brace?

If we take the angle 60° as the angle from the ground to the beam and let x be the distance from the base of the billboard to the bottom of the brace, the trigonometric equation which would best represent the scenario is,
                                     x = (20 ft) (cos 60°)
                                         x = 10 ft
Thus, the distance from the base of the billboard to the bottom end of the brace is 10 ft.
