hope it helps you . please mark thanks

Answer 2

Step-by-step explanation:

1. x + x + 20 = 180

2x + 20 = 180

2x = 160

x = 80

x= 80, x + 20

80+20= 100

100+80= 180°

ans is x = 80

2. x + 120 + x = 180

2x = 180-120= 60

x = 30

30 + 120 + 30 = 180°

ans is x = 30°

3. 3x + 2x =180

5x = 180

x = 180/5 = 36

3x

3*36= 108°

2x

2* 36 = 72°

108+72=180°

ans x = 36

4. not solve

5. 2x-10 + 40 + 2x - 10

2x- 10+40+2x-10= 180

4x +20 = 180

4x = 160

x= 40

2x - 10

2*40-10= 70°

70+40+70 =180°

ans x = 40

6. x + 2( x- 30°) = 180°

x + 2x - 60°

3x = 180+60

3x = 240

x= 80

x + 2 ( x - 30) = 180

80 + 2 ( 80-30) = 180

80+ 2 ( 50) = 180

80+100 = 180

and is x = 80
