When Donelle stands at point R, he is 1000 feet from point S at the base of a cliff. When he looks up at an angle of 20°, he sees a friend at the top of the mountain cliff at point T. Which measurement is the closest to the height of the mountain cliff in feet?

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

first one because it can't have a fraction in it

step-by-step explanation:

the answer is 8/21

hope this
