1. 130°
I don't remember too many specifics from my past math classes, but I always remembered this because that is an upside-down mirror of the 130° angle.
2. 50°
A straight line is 180°, and 180 - 130 = 50.
Y=140 because U have to go 35 divided by 2 and 8 times 17.5
No because at the 13 min mark she is at 10.2 not just 10
