Answer:
x > -2
Step-by-step explanation:
3(1 – x) < 9
Divide each side by 3
3/3(1 – x) < 9/3
1-x < 3
Subtract 1 from each side
1-x-1 < 3-1
-x < 2
Multiply each side by 1, remembering to flip the inequality
-x*-1 > 2*-1
x > -2
Open circle at -2, line going to the right
Answer:
Step-by-step explanation:
Let the exterior angle = x
Interior angle = 5x
x + 5x = 180 { interior angle and exterior angle are linear pair}
6x = 180
x = 180/6
x = 30
Interior angle = 5*30 = 150
