Answer:
B. 126 degrees
Step-by-step explanation:
lets say the angle is x
the equation we have here is the 8th graders divided by the total number of students is equal to x divided by 360 degrees since a circle has a 360 degree angle.
The equation is:
350/1000=x/360
in number form.
350/1000= 0.35 = 35%
so now we know x/360=35%
126/360=35%
so the answer would be 126 degrees.
