Answer:
The Total sum of exterior angles always will be 360
Step-by-step explanation:
therefore according to the 1st diagram
75 + 77 +60 + x + (180-135) = 360
257 + x = 360
x = 360-257
x = 103
75 + 50 +67 + x +x + x = 360
192 + 3x = 360
x = (360-192)/3
x = 56
also if you want to find the above variables using interior angles....you must use the following equation to find the total sum of interior angles..
(n - 2)*180
n = no of sides
