Answer:
C) x = 5√3
Step-by-step explanation:
This is a 30°-60°-90° triangle, which means that the sides opposite these angles have the relation of 1-√3-2.
Here, x is the 1, and 15 is the √3. That means that x/15 = 1/√3
Cross-multiply/Means-extremes: 15 = x√3
Divide: x = 15/√3
Simplify: x = (15√3)/3
Simplify: x = 5√3
