Question

if 5 10 theta minus 4 is equal to zero then the value of 5 Sin Theta - 4 cos theta upon 5 sin theta + 4 cos theta ​

Answer 1

The value of  $\frac{5\sin\theta -4\cos\theta}{5\sin\theta +4\cos\theta}$ is 0

Step-by-step explanation:

given : $5\tan\theta -4 =0$

then

$\frac{5\sin\theta -4\cos\theta}{5\sin\theta +4\cos\theta}$

dividing the numerator and denominator by  $\cos\theta$

we get

$\frac{\frac{5\sin\theta}{\cos\theta} -\frac{4\cos\theta}{\cos\theta}}{\frac{5\sin\theta}{\cos\theta} +\frac{4\cos\theta}{\cos\theta}}$

$\frac{5\tan\theta -4}{5\tan\theta +4}$

we know that

$5\tan\theta -4 =0$ therefore

$\frac{0}{5\tan\theta +4}=0$

hence , The value of  $\frac{5\sin\theta -4\cos\theta}{5\sin\theta +4\cos\theta}$ is 0
