Supplementary: Angles that add up to 180 degrees.
This means that angle 1 and angle 2 add up to 180 degrees. You can put them into an algebraic problem like I have in this (the image I have added), and solve for what x is. That is the key to finding out what angle 1 equals!
Once you have found x you can plug it into the equation you have for angles 1 and 2 to find if they equal 180.
Hope this helps!
1. h - 16 ≤ 24
+ 16 + 16
h ≤ 30
Solution Set: {h|h ≤ 30}, (-∞, 30]
2. y + 6 ≥ -13
- 6 - 6
y ≥ -18
Solution Set: {y|y ≥ -18}, [-18, ∞)
3. -3 < n - 8
+ 8 + 8
5 < n
n > 5
Solution Set: {n|n > 5}, (5, ∞)
4. 3 ≤ m + 1.4
- 1.4 - 1.4
-1.6 ≤ m
m ≥ -1.6
