Question

if 3sin A=18 then the value of cosec A is...​

Answer 1

Answer:

Option A) 18/3 is the correct answer

Step-by-step explanation:

Given,

$\: \: \: \: \: \: \: \: \sf \: 3 \: sin A = 18 \\ \sf \implies \: sinA = \frac{18}{3} \\ \\ \bf \: we \: know \: that \: \\ \sf \: cosecA = \frac{1}{sinA} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \sf = \frac{1}{ \frac{18}{3} } \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{3}{18} \\ \\ \green{ \boxed{ \sf \therefore \: cosecA = \frac{3}{18} }}$

Answer 2

*Question:—

if 3sin A=18 then the value of cosec A is

†Answèr:—

• (B) 3/18

‡Step by Step explanation:—

→ 3sinA = 18

→ sinA = 18/3

‡Now,

→ CosecA = 1/sinA

→ CosecA = 1/18/3

→ CosecA = 3/18

Hence we got the answer 3/18.
