hi just want to ask how do you calculate the value of tanA in degrees? bcos the range is 90
Question asked you to determine the value of tan A... not the value of the angle A. The domain given just tells you whether your value of tan A is negative (quadrant 2 in this case) or positive (Q1 and Q3)
To anonymous:
A is an angle in degrees.
tan A is actually a ratio of two lengths: the length “opposite” to angle A and the non-hypotenuse length “adjacent” to angle A.
In other words, tan A is not an angle; rather, it is kind of a length ratio measure.
For this question, we attempt to calculate our answer without having to know what angle A is.
