Pls Let me know if,

c = 360 - a - A - B - 2b (assuming a,b is different from A,B)

If they are the same, then c = 360 - 2a - 3b

In any triangle, sum of the 3 angles is 180 degrees.

I have marked the 3 angles unknow as x, y and z

from the 3 triangles,

y = 180 - a - b
x = 180 - a - b
z = 180 - b - c

Now, x + y + z = 180 (because they together form a straight line which is 180 degrees).

so, 180 - a - b + 180 - a - b + 180 - b - c = 180
=> c = 360 - 2a - 3b

the sum of the angles in a quad = 360

ie

2a + 3b +c = 360

=> c = 360 -2a-3b
