Answer:
B) 1/2
Step-by-step explanation:
The angle of the sector is also equal to the arc measure of the circle. This is because a sector is made up of two radii of a circle.
A circle is 360 degrees.
60 / 360 = 1/6
The sector is 1/6 of the circle.
Hope this helps!! :)
80 + 60 + y = 180 and if y and x are vertical angles y = x
