Answer:
20
Step-by-step explanation:
The angles are vertical angles which means they are equal
60 = 2x+20
Subtract 20 from each side
60-20 = 2x+20-20
40 =2x
Divide by 2
40/2 = 2x/2
20 =x

Multiply 1/6 by 1/6 by 1/6 essentially
(1/6)^3
1/216
The area of the "aob" secor is given by:
A = (S '/ S) * (pi) * (r ^ 2)
Where,
S '/ S = relation of arcs
r: radius of the circle
Substituting values we have:
A = (145/360) * (3.14) * (2 ^ 2)
A = 5.058888889
Rounding off we have:
A = 5.1 yd ^ 2
Answer:
the area of sector "aob" is:
A = 5.1 yd ^ 2
