mr Scott had 21 students in her class. she wanted to organize the desk in rows, with an equal number of desk in each row. she wanted more than 1 row. What was the least number of rows she could use

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.

215.92 dollars is the answer
