Step-by-step explanation:
Since the fractions have the same denominator, all we have to do is subtract the numbers in the numerator:
15 - 3 = 12
The difference of the two fractions is
. To simplify this answer, divide both the numerator and the denominator by 4:
12/4 = 3
20/4 = 5
The difference in simplified form is
.

Think: "Find <span>tan-1(0.577)" means "Find the ANGLE in Quadrant III whose tangent is 0.577. Because the angle is in QIII, both the opp side and the adj side are negative. Here you have four answer choices. The correct answer MUST be within the interval 180 and 270 degrees. Only one of the given answer choices satisfies that criterion. Which one is it?
