Let the base of the quadrilateral be 1 unit.
a = 180-24-48-30
a = 78°
(1/sin24) = (b/sin78)
b = 2.4048671724 units.
c = 180-48-24-42
c = 66°
(2.4048671724/sin66) = (d/sin66)
d = 2.4048671724 units.
e² = 2.4048671724²+1²-2*2.4048671724cos30
e = 1.6180339888 units.
(1.6180339888/sin30) = (1/sinx)
Where x is the angle we are are calculating.
It implies;
x = 17.9999999997°
x = 18°
