3 0

Answer:

32

Step-by-step explanation:

40 = 100%

how many are 80% ?

well, 80% = 80× 1%

1% = 100% / 100

so, in our case

80% = 80×40/100 = 8×4 = 32

as a shortcut you consider a percentage x as a ratio factor of x/100 you multiply the 100% number with.

in our case

80% = 40 × 80/100 = 32

How do you find arc ab
Marta_Voda [28]
Use trigonometry to find the angle between the segments 3 and 6.
  ∠XOB = arccos(3/6) = 60°

The measure of arc AB is double that angle, since the figure is symmetrical about the line containing the segment of length 3.

m(arc AB) = 2·60° = 120°
