Question

find the unknown angle X in each of the following figures
pls answer ​

Answer 1

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
