Answer:

Explanation:

Because all of the numbers have a degree symbol, we know that they all add together to make 360° since that's how many degrees there are a circle.

4x + 6x + 7x + 7x = 360

Then, we solve for x

24x = 360

x = 15

Then, add the two degrees with the red arc.

6(15) + 7(15) = 195°

The length of the red arc is 195°
