Answer 1

Answer:

1. 2x+4x+3x = 180

9x=180

x=180/9

x=20

therefore the first angle is = 2x

2x20=40

second angle =3x =3x20=60

third angle =4x=4x20=80

40+60+80=180

Answer 2

Answer:

1) 2x +3x+4x=180

9x =180

x=180÷9=20

2x= 2×20=40

3x=3×20=60

4x=4×20=80

2) 2x+3x+90=180

5x+90=180

5x=180-90=90

x=90÷5=18
