Mr. B works in a factory with his two sons. He is really happy because he gets to spend time with them at work! He is allowed to take a break every 140 minutes, while his sons can take breaks in 210 minutes and 280 minutes. How many minutes will they have to wait after their first break to get together again?

so then what are you asking?

step-by-step explanation:

central angle of a triangle has the same measure as its intercepted arc.

step-by-step explanation:

let's first notice, the center of the hyperbola is at the origin, since the focus points are equidistantly 3 units away from the origin, that also means that the distance "c" from the center to either focus is 3.

it should also be notable that, the traverse axis for this hyperbola is vertical, or namely over the y-axis and therefore, the positive fraction will be the one with y-variable.

the traverse "a" component or distance from the center to either vertex is not 2, is more than 2, so we can safely put it at √5 ≈ 2.24.
