Question

if 3 tan tetha =4 find value of 4cos theta -sintetha​

Answer 1

Answer: 8

Step-by-step explanation:

Given : $3\:\tan\theta\:=\:4$

Or $\tan\theta\:=\:\dfrac{4}{3}$

We know that tan = sin / cos

So from here the values of sin and cos are 4 and 3 respectively ,

Put these values in the equation ,

= 4 cos theta - sin theta

= 4 × 3 - 4

= 12 - 4

= 8
