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
20 miles
25.4 miles
29.4 miles

Check the picture below.

15 miles

Step-by-step explanation:

Please refer to the picture attached to this .

here we are given that the Main street and the first street meets at right angle and the oak street makes the hypotenuse to the right angle triangle thus formed.

we are given that the angle formed by the first stree and the oak street is x and tan x = 7/5

Also by trignometric ratios

FSD = First street distance

Hence car B has to drive 15 miles on first street to reach oak street

the answer is a
