Answer:
x = 40°
Step-by-step explanation:
Sum of angles on a line = 180°
∴ 2x - 10 + 40 + 2x - 10 = 180°
∴ 4x + 20 = 180°
∴ 4x = 180 - 20
∴ x = 160/4
∴ x = 40
ANSWER:
x = 40°
You can test this answer by substituting the value of x into the actual figure. The result should come as 180. If it does, you're on a roll!
2(40) - 10 + 40 + 2(40) - 10
= 80 - 10 + 40 + 80 - 10
= 200 - 20
= 180!
Yay! Your answer is right! Full marks guaranteed!!
