Answer:
15√3.
Step-by-step explanation:
This is a 30-60-90 right triangle.
The sides are in the ratio 2:1:√3 where 2 is the hypotenuse, side of length 1 is opposite 30 degree angle and side √3 is opposite the 60 degree angle.
So as the side opposite the 30 degree angle = 15,
x = 15 * √3
= 15√3.
Answer:
15√2 (fourth answer choice)
Step-by-step explanation:
Note that the ratio 15/x is the tangent of 30 degrees, which in turn is 0.577 or 1/√2. Then:
1/√2 = 15/x, or
1 5
----- = ----- or x = 15√2
