Angle 1 and 3 are vertical angles, which mean they are identical. Since angle 3 is given as 111 degrees, then angle 1 is also 111 degrees.

All four angles need to equal 360.

Subtract angle 1 and 3 from 360:

360 - 111 - 111 = 138

Angle 2 and 4 would also be identical, so divide the 138 by 2:

138 / 2 = 69

Angle 2 and angle 4 are both 69 degrees.

It will take 5.25 hours to the second car to overtake the first car, and the first car will have traveled during 8.25 hours.

Why?

To calculate how long before the second car overtakes the first one, we need to make the equations of both cars equal.

For the first car, we have:

$x=x_o + v_{1}*t\\\\x=x_o + v_{1}*(3 hours + t)$

For the second car, we have:

$x=x_o + v_{2}*t\\\\x=x_o + v_{2}*(t)$

Making both equations equal, we have:

$35mph*(3hours+t)=55mph*t\\\\105+35t=55t\\\\105=55t-35t\\\\t=5.25$

Hence, we have that it will take 5.25 hours to the second car to overtake the first car, and the first car will have traveled during 8.25 hours.

Have a nice day!
