Question

3 cos A - 4 sin A = 2 cos A + sin A find A​

Answer 1

Answer:

A = 11.31° [Aproximately]

Step-by-step explanation:

We have,

3CosA - 4SinA = 2CosA + SinA

3CosA - 2CosA = 4SinA + SinA

CosA = 5SinA

1 = 5(SinA/CosA)

We know that,

SinA/CosA = TanA

Hence,

5TanA = 1

Tan A = (1/5)

Taking,

Tan^(-1) (1/5) = 11.30°

Hence,

A = 11.309932474°

So,

A = 11.31° [Aproximately]
