Question

question 9 (1 point)
the point (2, -3) is on the terminal arm of db.which is the correct value of cot b?
o a) - 3/2
o b) - 2/3
o c) 2/√13
o d) - 3/√13

Explanation:

Step1: Recall the formula for cotangent

For a point \((x,y)\) on the terminal arm of an angle, \(\cot B=\frac{x}{y}\).

Step2: Substitute \(x = 2\) and \(y=-3\)

\(\cot B=\frac{2}{-3}=-\frac{2}{3}\)

Answer:

B. \(-\frac{2}{3}\)
