Answer:
a
Step-by-step explanation:
Diameter is 16 so radius is 8 feet.
Area of the sector is 8 square feet = 1/2*r^2*(angle)
8/ (0.5*8^2)= angle
angle = 0.25
Assuming the sum of the opposite angle would be 180. We can easily calculate for x and ultimately solve for the angle of B. We do as follows
B + D = 180
3x-12 + x = 180
4x - 12 = 180
4x = 192
x = 48 degrees
Therefore angle B would have a measurement of 132 degrees. Hope this helps.
