Answer:

Option A

Step-by-step explanation:

30° - 60° - 90° triangle:

       The ratio of the side of 30-60-90 triangle is x : x√3 : 2x

 The angle opposite to 90° = 2x

            2x = 10

              x = 10÷2

               x = 5

The side opposite to 30° is x which is 5.

The side opposite to  60° is x√3 = 5√3

The ratio of sides of 30-60-90 triangle:

        5 : 5√3 : 10
