One automobile starts out from a town at 8 a. m. and travels at an average speed rate of 60mph. 2 hours later, a second automobile starts out to overtake the first. If the second automobile travels at an average rate of 80mph, how long will it travel before it overtakes the first?

y=x+9

?

step-by-step explanation:

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

6e14 is the answer.

answer: 0.1,0.85
