    cool, so it's just algebra from here you have a straight line, so half a revolution, so half of 360, so total is 180 degrees

    so solve for x first, then solve for m<DBC 7x + (x-4) = 180 can u solve for x from here?

    u have a straight line that is bisected, so ignore the bisection and concentrate on the straight line first straight line = 18 degrees
