Answer:
34.01
Step-by-step explanation:
Circumference = Diameter * π
106.81 = Diameter * π
Diameter = 34.01
4/5 = 0.8 which would be 80%
I would say x=30 y=90
because
(y+x)
90+30=120
(y-x)
90-30=60
the sum of those 2 angles should equal 180 because they are supplementary angle.
120+60=180
and because the angles of 2x and y+x are also supplementary they should equal 180
2x
2(30)
=60
(y+x)
90+30
=120
120+60=180
