Answer 2

Answer :-

Option [B]

Cosec A = 3/18

Step-by-step explanation :-

Given:

• 3 sin A = 18

To find:

Value of Cosec A = ?

Concept used:

Cosecant of A abbreviated as cosec A is the reciprocal of sin A.

Cosec A = Hypotenuse ÷ Adjacent side

Solution:

3 × sin A = 18

⇒ sin A = 18 ÷ 3

⇒ sin A = 18/3

Cosec A = 1 ÷ sin A

⇒ Cosec A = 1 ÷ 18/3

⇒ Cosec A = 3/18

∴ Cosec A = 3/18
