Answer:
x > –3; 5y ≥ –4x – 10
Step-by-step explanation:
The dashed vertical line is the inequality x > -3 or x < -3. All vertical lines have the form x = a. Since it is dashed then the sign must be < or >.
The solid line has a y-intercept at -2 and a slope of -4/5. This means it must be the equation y ≥ -4/5x -2 or y ≤ -4/5x - 2. This is the same equation as 5y ≥ -4x - 10.
So the solution is x > –3; 5y ≥ –4x – 10.

Answer:
Step-by-step explanation:
m∠ABC + m∠BAC + m∠ACB = 180°
a + 2a + 6a = 180°
9a = 180°
a = 20°
m∠ABC = 20°
m∠BAC = 2 × 20° = 40°
m∠ACB = 6 × 20° = 120°
