How do you find arc ab

Mathematics
1 answer:
Marta_Voda [28]3 years ago
7 0
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°

Is 192 rational , why is it?
Oduvanchick [21]

Answer: 192 IS IRRATIONAL. I HOPE THIS ANSWER HELPS.

Step-by-step explanation:

It is an irrational number if it is not a perfect square. Since 192 is not a perfect square, it is an irrational number. This means that the answer to "the square root of 192?" will have an infinite number of decimals. The decimals will not terminate and you cannot make it into an exact fraction.
