Question

Sin3A=COT A-6 find A​

Answer 1

Hi mate

Here is ur answer...

sin 3A = cot (A-6)

cot (90 - A+6)= tan (96 - A )

sin 3A = tan (90- A)

sin 3A = sin/cos ( 90-A)

3A=1/cos (90-A)

3A=sec(90-A)

3A= cosec A

A=cosecA / 3

Answer 2

Answer:

Step-by-step explanation:sin a=(90-a)

Sin 3a=(90-3a)

90-3a=a-6

3a+a=90+6

4a=96

A=96/4

A=24
