George has two different sprinklers. The first sprinkler waters an arc of 42 yd, and has a radius of 21 ft. If the second sprinkler waters the same central angle, and has a radius of 27 ft, what is the length of the arc it waters?

answer: i don't understand. what are the options

step-by-step explanation:

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100

step-by-step explanation:

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.

i don't think there is enough
