What was the rate on 6-year $5000 loan that paid $3600 interest?

12

Step-by-step explanation:

3600*100= 360000

5000*6=30000

360000/30000= 12

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
