Answer: 
Step-by-step explanation:
Let the smallest angle be x.
Then, the middle angle is x+30.
The largest angle is 2x+30.
Angles in a triangle add to 180 degrees, so:

So, the angles measure 
Answer:
5 x 10-6

Answer:

Step-by-step explanation:
Isolate the 3m by adding 4 to every part of the inequality:
-9 ≤ 3m - 4 < 11
-9 + 4 ≤ 3m -4 + 4 < 11 + 4
-5 ≤ 3m < 15
Now, divide every part of the inequality by 3:
