Answer:

Step-by-step explanation:
tan 3x=\frac{\sqrt{3} }{3} =\frac{1}{\sqrt{3} } =tan\frac{\pi }{6} =tan (n\pi +\frac{\pi }{6} )\\3x=n\pi +\frac{\pi }{6} =\frac{(6n+1)\pi }{6} \\x=\frac{(6n+1)\pi }{18} \\
where~x~is~an~integer.
Multiply secondsn by 60 add to minutes multiply by 60 and to degrees
Diagram please
Without diagram I cannot tell you the answer
Measure 1 would be 59 degrees (180-121)
Measure 2 would be 121 degrees (vertical angle theorem)
Divide miles by 60 to convert it to miles per minute because there are 60 minutes in an hour.
