Question

$\sf \: Find \: the \: value \: of \: cosec \: 150 \degree$

​

Answer 1

Answer:

2

Step-by-step explanation:

Given that: Cosec 150°

=>Cosec (90°+60°)

=>Sec60°

=> 2

or Cosec150°-Cosec (180°-30°)

=>Cosec30°

=>2

$\sf \: cosec(x) \: is \: defined \: as \: \frac{1}{sin(x)} \: \: \\ \sf \: therefore \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \sf \: cosec (150 \degree) = \frac{1}{sin(150 \degree) } = 2$
