Question

If cosec A = a/b , find the value of cotA

Answer 1

Answer:

1/2 is your answer mark me as brainliest

Answer 2

Answer:

Given

Cosec ( A - B ) = 2

And

Cot ( A + B ) = 13

Se an write these equations As :

Cosec ( A - B ) = Cosec 30 ( As we know Cosec 30 = 2 )

So,

A - B = 30 --------------------- ( 1 )

And

Cot ( A + B ) = Cot 60 ( As we know Cot 60 = 13 )

So,

A + B = 60 ---------------------- ( 2 )

Now we add equation 1 and 2 and get

2A = 90

A = 45 ( Substitute that value in equation 2 and get )

45 + B = 60

B = 15

SO,

A = 45 And B = 15
