Answer:
Option c
Step-by-step explanation:
We are given that the post office is at the corner of first street and main street and they form right angled .
We have to find the distance travel by car B to reach Oak street from First street
Let x be the distance traveled by car B on First street to get to Oak street
In right angled triangle NOE
OE=14 miles
NO=x
[tex]tany^{\circ}=\frac{5}{7}[/tex]
[tex]tan\theta=\frac{opposite \;side\; of\; angle\; y}{adjacent\; side \;of\; y}[/tex]
[tex]\frac{5}{7}=\frac{x}{14}[/tex]
[tex]x=\frac{5\times 14}{7}[/tex]
[tex]x=10 miles[/tex]
Therefore, option c is true.
