Answer:
a) x+2x+3x = 180
b) 30
Step-by-step explanation:
a - the angle of a straight line is 180 in total.
b - x+2x+3x = 180
6x = 180
x = 30
(just adding the x's and dividing them in 180 in order to find the value of individual x's.)

Step-by-step explanation:
(a) x° + 2x° + 3x° = 180° (angles on a straight line)
(b) x° + 2x° + 3x° = 180°
→ 6x° = 180°
→ x° = 180°/6
→ x° = 30°
