1. 3x+6   +   x+2  = 180

4x = 172

x = 43        A= 3x+6 = 3 x 43   + 6 = 135 degrees

2 and 3 are similar

Second one :

4x - 20  + x   =  180

5x - 20  =  180     add 20 to both sides

5x  = 160    divide both sides by

x  = 32°

Third one :

116 + x   = 180     subtract  116 from both sides

x  = 64

So A = 2(64) - 40  =  128 - 40  =  88°

Last one :

x + 10  + x + 24  =  180

2x + 34  =  180      subtract 34 from both sides

2x  = 146         divide both sides by 2

x  = 73

So

A + C  = 180

(x + 15) +   C   =  180

(73 + 15) + C  = 180

88 + C   =  180  subtract 88 from both sides

C  = 92°
