The formula to calculate the Distance (D) from an Angle is:
\[ D = \frac{H}{\sin(a)} \]
Where:
Distance from an angle refers to the horizontal distance measured from a point at a certain height, forming a triangle with the ground.
The distance \( D \) can be calculated using the height \( H \) and the angle \( a \) (measured in degrees).
Given:
Calculate the Distance (\( D \)):
\[ D = \frac{10}{\sin(30^\circ)} \]
Using a calculator or sin table, \( \sin(30^\circ) \approx 0.5 \).
\[ D = \frac{10}{0.5} = 20 \text{ meters} \]
Therefore, the distance (\( D \)) from the angle is approximately 20 meters.
