The y-coordinate of the point is approximately 2.42.
Step-by-step explanation:
From the figure attached below the statement we derive the following equation to calculate the y-coordinate (), dimensionless, of the point in terms of the x-coordinate (), dimensionless, and angle of the line (), measured in sexagesimal degrees:
(1)
If we know that and , then the y-coordinate of the point is:
The y-coordinate of the point is approximately 2.42.
well, let's assume a year has 365 days, so 75 days is simply 75/365 of a year. We also know that your loan was $650 and you paid back $680 or namely 30 bucks extra, so the interest on those $650 is really 30 bucks.
In a right triangle, the square of the largest side is equal to the sum of the squares of the smaller sides, so if you plug the sides in to that equation, you should get zero if those sides form a right triangle. B is the only option where this is true, so I believe set B defines a right triangle.
