## Base angle (α) of Square Pyramid Solution

STEP 0: Pre-Calculation Summary
Formula Used
angle_a = arccos((((Side A/2)^2)+(Slant Height^2)-(Height^2))/(Side A*Slant Height))
∠A = arccos((((a/2)^2)+(s^2)-(h^2))/(a*s))
This formula uses 2 Functions, 3 Variables
Functions Used
cos - Trigonometric cosine function, cos(Angle)
arccos - Inverse trigonometric cosine function, arccos(Number)
Variables Used
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)
Slant Height - Slant Height is the height of a cone from the vertex to the periphery (rather than the center) of the base. (Measured in Meter)
Height - Height is the distance between the lowest and highest points of a person standing upright. (Measured in Meter)
STEP 1: Convert Input(s) to Base Unit
