Angle A of Cyclic Quadrilateral Solution

STEP 0: Pre-Calculation Summary

Formula Used

Angle A of Cyclic Quadrilateral = arccos((Side A of Cyclic Quadrilateral^2+Side D of Cyclic Quadrilateral^2-Side B of Cyclic Quadrilateral^2-Side C of Cyclic Quadrilateral^2)/(2*((Side A of Cyclic Quadrilateral*Side D of Cyclic Quadrilateral)+(Side B of Cyclic Quadrilateral*Side C of Cyclic Quadrilateral))))
∠A = arccos((S_a^2+S_d^2-S_b^2-S_c^2)/(2*((S_a*S_d)+(S_b*S_c))))
This formula uses 2 Functions, 5 Variables

Functions Used

cos - Cosine of an angle is the ratio of the side adjacent to the angle to the hypotenuse of the triangle., cos(Angle)
arccos - Arccosine function, is the inverse function of the cosine function.It is the function that takes a ratio as an input and returns the angle whose cosine is equal to that ratio., arccos(Number)

Variables Used

Angle A of Cyclic Quadrilateral - (Measured in Radian) - Angle A of Cyclic Quadrilateral is the space between two adjacent sides of the Cyclic Quadrilateral, forming angle A.
