Diagonal length of a convex quadrilateral (given area,angle and another diagonal)

Formula

Diagonal length of a convex quadrilateral (given area,angle and another diagonal) formula
p
length of one diagonal
S
area
q
length of another diagonal
theta
angle between p and q

Formula description

A quadrilateral is a polygon with four sides (or edges) and four vertices or corners. Quadrilaterals are simple if it is not self-intersecting. Simple quadrilaterals are either convex or concave. The area can be expressed in trigonometric terms if lengths of two diagonals and the angle between them are known.
