Answer:
The correct answer is option A. √3
Explanation:
From the figure we can see that aright angled triangle.
Points to remember
If a right angled triangle with angle 30°, 60° and 90° then the sides are in the ratio, 1 : √3 : 2
To find the length of side opposite to 30°
Let 'x' be the side opposite to the 30°, the we can write,
x : 3 : Hypotenuse = 1 : √3 : 2
Therefore x = 3/√3 = √3
The length of side opposite to the 30° is √3
The correct answer is option A. √3
