Given 3 cosA - 4 sinA = 0; evaluate without using tables: sinA + 2 cosA / 3 cosA - sin A.

11/9

Step-by-step explanation:

3cosA-4sinA=0

cosA=4/3sinA

3 cos A - 4 sin A = 0

To Evaluate:

Transposing 4 sin A to RHS,

Transposing 4 to LHS and cos A to RHS,

So,

Now, as ,

And,

We need to find that,

So,

So,

So,

Answer:-

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
