Answer:

To solve this problem, we can use trigonometry.

Let's assume that X is the height of the object, and A is the distance from the object to the point where the angle of elevation is measured.

We can use the tangent function to relate the angle of elevation to the height and distance:

tan(angle) = height / distance

Plugging in the given values, we have:

tan(15°) = X / 12m

Now, we can solve for X by multiplying both sides of the equation by 12m:

X = 12m * tan(15°)

Using a calculator, we can evaluate the expression:

X ≈ 3.28m

Therefore, the closest option to the height X is 3.3 m (option C).
