Question

If tanA=3,than 4 sin A-3 cosA/4sin A+3cosA=

Answer 1

Answer:

3/5

Step-by-step explanation:

given

tanA=3

SinA/cosA = 3

so

SinA=3CosA

so

given question

[4SinA-3CosA]/[4SinA+3CosA]

put value of sin as in terms of cos

so

[4*3CosA - 3*3CosA]/[4*3CosA+3CosA]

CosA[12-3]/CosA[12+3]

9/15

3/5
