What is the value of sin(60 degrees) in a right-angled triangle with a hypotenuse of 2 units and the side opposite the 60-degree angle of sqrt(3) units?
Correct: B
In a right-angled triangle, sin(theta) = opposite side / hypotenuse. Given the hypotenuse is 2 units and the side opposite the 60-degree angle is sqrt(3) units, sin(60 degrees) = sqrt(3) / 2.
