Answer:
Angle 1 is 30° and angle 2 is 150°
Step-by-step explanation:
- <em>Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.</em>
Let angle 1 is a, angle 2 is b and we got b = 5a
- a + 5a = 6a
- 6a = 180°
- a = 180°/6
- a = 30°
and
X = 9. This is because if we add 1 to both sides (to make it easier to isolate x), then we get 2/3=6. Multiplying both sides by 3, we get 2x = 18. Dividing both sides by 2 (to isolate x), we get x = 9. I hope this helps! :D
