Solution:
Steps of Statement: We will solve right Angled ∆ RST. We will use Trigonometric Ratio to solve this Question.
Now, In ∆ RST , Where angle C is 90° and angle D is 60°
∠RTS = 60°
So, Sin 60° = RS / RT
☛ √3/2 = 2√3 / RT
☛ RT = 4
Now, Let's Solve Right angled ∆ QRT
tan 45° = QR / RT
☛ 1 = x / 4
☛ x = 4
Therefore, Required Value of x is 4.
