Apound of popcorn is popped for a class party. the popped corn is put into small popcorn boxes that each hold 120 popped kernels. there are 1,450 kernels in a pound of unpopped popcorn. if all the boxes are filled except for the last box, how many boxes are needed and how many popped kernels are in the last partially filled box?

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
