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°
