the post office is at the corner of first street and main street, which forms a right angle. first street intersects with oak street to the north, and main street intersects with oak street to the east. the intersection of first street and oak street forms an x° angle, and tan x° = seven fifths. car a drives on main street for 21 miles to arrive at oak street. how far will car b have to travel on first street to get to oak street? round your answer to the nearest tenth of a mile.

  15 miles

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you that ...

  Tan = Opposite/Adjacent

  tan(x°) = (Main street length)/(First street length) = 7/5

Then the length of First street from Main to Oak is ...

  First street length = (Main street length)/(7/5) = (21 miles)×(5/7)

  First street length = 15 miles

step-by-step explanation:

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.
