## First angle of Kite Solution

STEP 0: Pre-Calculation Summary
Formula Used
angle_a = arccos(((Distance Between the Points^2)+(Side A^2)-(Diagonal 2/2)^2)/(2*Distance Between the Points*Side A))
∠A = arccos(((dl^2)+(Sa^2)-(d2/2)^2)/(2*dl*Sa))
This formula uses 2 Functions, 3 Variables
Functions Used
cos - Trigonometric cosine function, cos(Angle)
arccos - Inverse trigonometric cosine function, arccos(Number)
Variables Used
Distance Between the Points - Distance Between the Points Contributing to the change in Head. (Measured in Meter)
Side A - Side A is an upright or sloping surface of a structure or object that is not the top or bottom and generally not the front or back. (Measured in Meter)
Diagonal 2 - The Diagonal 2 is the line stretching from one corner of the figure to the opposite corner through the center of the figure. (Measured in Meter)
STEP 1: Convert Input(s) to Base Unit
Distance Between the Points: 10 Meter --> 10 Meter No Conversion Required
Side A: 8 Meter --> 8 Meter No Conversion Required
Diagonal 2: 10 Meter --> 10 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
∠A = arccos(((dl^2)+(Sa^2)-(d2/2)^2)/(2*dl*Sa)) --> arccos(((10^2)+(8^2)-(10/2)^2)/(2*10*8))
Evaluating ... ...
∠A = 0.518123594506538
STEP 3: Convert Result to Output's Unit
0.518123594506538 Radian -->29.6862952313779 Degree (Check conversion here)
29.6862952313779 Degree <-- Angle A

## What is a kite?

In Euclidean geometry, a kite is a quadrilateral whose four sides can be grouped into two pairs of equal-length sides that are adjacent to each other. In contrast, a parallelogram also has two pairs of equal-length sides, but they are opposite to each other instead of being adjacent.
