A. 485 is %3 of 500, but the deviation sets it slightly lower than that
Area of the sector = 1/2 * r^2 * theta where theta is the angle subtended by the arc at the center ( in radians)
In this case m < theta = 360 - 235 = 125 degrees or 2.182 radians
So, the area of shaded area = 1/2 * 20^2 * 2.182 = 436.4 in^2
Answer:
98 degrees
angles of a triangle always add up to 180 degrees. 41+41= 82. 180-82= 98
C I think because it shows the months and the total
