It will take an hour for plane a to meet plane b which is flying in the opposite direction. if, in 45 minutes, the distance between them will be 200 miles, how far apart are they now?

answer:

step-by-step explanation:

60 minutes = x

45 minutes = 200 miles

then cross-multiply: 60*200/45x

12000/45x

x = 266

answer:

x=226

step-by-step explanation:

9 x 8 divided by (5-3)=36

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
