Question

Plzzzzz send help. I'll mark brainliest If cot = 1.5 and is in quadrant 3, what is the value of sin?

Answer 1

we can’t see a graph so we can’t help you. you can mark me brainliest anyway though.

Answer 2

Answer:

-0.55

Step-by-step explanation:

Use trig identity:

$1+ cot^2t = \frac{1}{sin^2t}$

$1+2.25 = \frac{1}{sin^2t}$

$sin^2t = \frac{1}{3.25}$

$sin t = + \frac{1}{1.80}$

Since t is in quadrant III, then sin t is negative

$sint = - \frac{1}{1.8} =-0.55$
