23. A surveyor needs to know the width of a flood control channel. From point A, she walks 100 feet to point B and sights to point C, as shown below.

From this sighting, the surveyor finds that the measure of ∠ABC is 50°. Which of the following is closest to the width, in feet, of the flood control channel?

(Note: sin 50° ≈ 0.766; cos 50° ≈ 0.643; tan 50° ≈ 1.192)
