Question

if sin 3a=1 then what is the value of 2a​

Answer 1

Answer:

answer is this

Step-by-step explanation:

sin3a = sin90°

this gives,

3a = 90°

a = 30°

therefore,

2a = 2 *30°= 60°

Answer 2

$Given \: sin 3A = 1$

$\implies sin 3A = sin 90\degree$

$\implies 3A = 90\degree$

$\implies A = \frac{90\degree}{3}$

$\implies A = 30\degree$

$Now, Value \:of \: 2A = 2 \times 30$

$= 60\degree$

Therefore.,

$\red{ Value \:of \: 2A}\green { = 60\degree}$
