To calculate the value of x, you can apply:

 Tan(α)=Opposite leg/Adjacent leg

 In this case, the opposite leg is "x", and the adjacent leg is 15. The angle α is 30° (α=30°)

 When we substitute this values, we obtain:

 Tan(α)=Opposite leg/Adjacent leg
 Tan(30°)=x/15
 x=(15)(Tan(30°))
 x=5√3

 What is the value of x?

 The answer is: The value of x is 5√3
