Find the general solution of the following equation. \( \sqrt{8} \sin x=2 \)

1 .\( \frac{\sin 210^{\circ} \cos 300^{\circ} \tan 240^{\circ}}{\cos 120^{\circ} \tan 150^{\circ} \sin 330^{\circ}} \) \( \left..3 \sin (-\theta)+\cos (360-0)] \left\lvert\, \cos (90-0)+\frac{\sin \theta}{\tan \theta}\right.\right] \) If \( \tan x=m+\frac{1}{m}, 90^{\circ} \leq x \leq 270^{\circ} \) and \( m^{2}+\frac{1}{m^{2}}=1 \) Calculate the value of \( x \) without the use of a calculato

In \( \triangle Q W E, m \angle Q=45 \) and \( m \angle E=90 \). If \( E W=7 \), find \( Q E \) and \( Q W \).

\( \begin{array}{llll}\text { (B) } \frac{1}{\sqrt{2}} & \text { (B) } \sqrt{3} & \text { (C) } \frac{1}{\sqrt{3}} & \text { (D) } \sqrt{2}\end{array} \) यदि एक मीनार की ऊंचाई तथा छाया की लंबाई समान हो, तो सूर्य का उन्नयन कोण है \( \begin{array}{llll}\text { (अ) } 30^{\circ} & \text { (ब) } 60^{\circ} & \text { (स) } 45^{\circ} & \text { (द) } 15^{\circ}\end{array} \) If the height of a tower and length of its shadow are same, then the angle of elevati \( \begin{array}{llll}\text { (A) } 30^{\circ} & \text { (B) } 60^{\circ} & \text { (C) } 45^{\circ} & \text { (D) }\end{array} \)

6.2 \( \left.\quad[\sin (-\theta)+\cos (360-\theta)] \left\lvert\, \cos (90-0)+\frac{\sin \theta}{\tan \theta}\right.\right] \)
