Question

What is the value of x? Enter your answer in the box. x =

Answer 1

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.
