7 is 45 degrees ndhdhdhdjdj
The answer is, C
2x +3y=7.20
4x+2y=8.80
Arc length from A to C (red line) is the given inside angle times 2, so AC = 50*2 = 100 degrees.
A full circle is 360 degrees, so arc ABC (blue line) would be 360 - 100 = 260 degrees.
The answer is D.
No because it fails the vertical line test hope it helps
