Distance Angle Calculator [ Triangle, Angular Size, Trigonometry ]

Divide the height (H) by the sine of the angle (a) to calculate the distance (D). The Distance Angle Calculator is a practical tool for determining the horizontal or diagonal distance to an object based on its height and angle of elevation.

This method is commonly used in trigonometry, surveying, and physics for tasks such as determining the distance to a building, calculating projectile motion, or optimizing viewing angles. By applying this formula, you can compute accurate distances in various real-world scenarios.

Formula:

$D = H / \sin(a)$

Variable	Description	Unit
$D$	Distance to the object	Meters (m) or feet (ft)
$H$	Height of the object	Meters (m) or feet (ft)
$a$	Angle of elevation	Degrees (°)
$\sin(a)$	Sine of the angle	Unitless

Solved Calculations:

Example 1: Calculate Distance with $H = 50 \, \text{m}$ and $a = 30°$

Step	Value	Explanation
Height ( $H$ )	50 m	The vertical height of the object
Angle ( $a$ )	30°	Given angle of elevation
Formula: $D = H / \sin(a)$	$D = 50 / \sin(30)$	Substitute values
Calculation	$D = 50 / 0.5$	Sine of 30° is 0.5
Result	$D = 100 \, \text{m}$	The calculated distance

Example 2: Calculate Distance with $H = 20 \, \text{ft}$ and $a = 45°$

Step	Value	Explanation
Height ( $H$ )	20 ft	The vertical height of the object
Angle ( $a$ )	45°	Given angle of elevation
Formula: $D = H / \sin(a)$	$D = 20 / \sin(45)$	Substitute values
Calculation	$D = 20 / 0.7071$	Sine of 45° is approximately 0.7071
Result	$D = 28.28 \, \text{ft}$	The calculated distance
