Answer:

The proof is explained step-wise below :

Step-by-step explanation:

\frac{1-\sin\theta}{1+\sin\theta}=7-4\sqrt3\\\\\implies \frac{1-\sin\theta}{1+\sin\theta}\times \frac{1-\sin\theta}{1-\sin\theta}=7-4\sqrt3\\\\\implies \frac{(1-\sin\theta)^2}{1-\sin^2\theta}=7-4\sqrt3\\\\\implies (\frac{1-\sin\theta}{\cos\theta})^2=7-4\sqrt3\\\\\implies(\sec\theta-\tan\theta)^2=7-4\sqrt3.......(1)\\\\\text{Now, taking the other given equation }\\\\\sec\theta-\tan\theta=\sqrt3-2\\\\\text{squaring both the sides}\\\\\implies(\sec\theta-\tan\theta)^2=7-4\sqrt3.......(2)

Now, using equation (1) and (2)

Hence Proved.
