If `sqrt(3)=1*732`, find (correct to two decimal places) the value of the following `sin60^(@)`

Text Solution

The correct Answer is:
To find the value of \( \sin 60^\circ \) given that \( \sqrt{3} = 1.732 \), we can follow these steps: ### Step 1: Recall the trigonometric ratio We know from trigonometric ratios that: \[ \sin 60^\circ = \frac{\sqrt{3}}{2} \] ### Step 2: Substitute the value of \( \sqrt{3} \) Now, substitute the given value of \( \sqrt{3} \) into the equation: \[ \sin 60^\circ = \frac{1.732}{2} \] ### Step 3: Perform the division Now, calculate \( \frac{1.732}{2} \): \[ \sin 60^\circ = 0.866 \] ### Step 4: Round to two decimal places Since the question asks for the value correct to two decimal places, we round \( 0.866 \): \[ \sin 60^\circ \approx 0.87 \] ### Final Answer Thus, the value of \( \sin 60^\circ \) correct to two decimal places is: \[ \sin 60^\circ \approx 0.87 \] ---
