Formula to get the Interior angle: 180(n-2), wherein n=sides
1. 4 sides
180(4-2)
180(2)
360
360=A+B+C+D
360=A+92+101+68
360=A+261
360-261=A
99°=A
2-4 same process lang siya sa 1. Get first the sum of interior angle using the formula= 180(n-2). Then proceed to the next step, which is by subtracting the given angle to the sum of interior angle to get the measure of A.
