question 9 (1 point)\nthe point (2, -3) is on the terminal arm of db.which is the correct value of cot b?\no a) - 3/2\no b) - 2/3\no c) 2/√13\no d) - 3/√13
Answer
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})
