Question

If $\sin(a + b) \: = \: \frac{ \sqrt{3} }{2}$ and
$\cosec \: a \: = \: 2$ , then find 'a' and 'b'.

Answer 1

Hi Mate!!!

Sin ( a + b ) = Sin ( 60 )

a + b = 60 .... equation 1

Cosec ( a ) = Cosec ( 30 )

=>. a = 30


put value of a in equation 1

30 + b = 60

=>. b = 30

and


a = 30

Answer 2

Answer: 30

Step-by-step explanation:

Sin ( a + b ) = Sin ( 60 )

a + b = 60 .... equation 1

Cosec ( a ) = Cosec ( 30 )

=>. a = 30

put value of a in equation 1

30 + b = 60

=> b = 30

and

a = 30...

Hope it helps....
