The factors of 21 are 1, 3, 7, and 21
Tan(angle) = opposite leg/ adjacent leg
Tan(30) = x/22
X = 22 * tan(30 )
X = 12.701 feet.
Round as needed
yellow car = x
white cars = 9x ( 9 times as many white cars)
9x +x = 40
10x = 40
x = 40/10 =4
4 yellow cars
9*4 = 36 white cars
To figure this out youll have to multiply 64.80 by 2.5 first then youll get 162 after to figure out the answer you subtract 20 from that amount and get 142
