Answer:
See below
Step-by-step explanation:
Basically, the associative property states that when an expression has three terms, they can be grouped in any way to solve that expression.
For example, 
if you're doing multiplication, or 
, if you're doing addition.
Answer:
The total angle (Angle FGH) = 141 degrees
Angle 1 = 59 degrees
To find this, all you need to do is subtract 59 degrees from 141 degrees.
Because Angle 1 and Angle 2 make up Angle FGH, which - 141 degrees.
141 degrees is your (considered) total amount of degrees, and 59 degrees is apart of it. So, 141 - 59 = 82 degrees.
Angle 2 = 82 degrees.
I hope this helps!

They have different like angles?
Answer:
1. 2
2. -9
3. 2+-9
4. -7
5. -15 + 8 = -7
Step-by-step explanation:
The surface of the water is 0. If Paula is above the surface of the water than she is positive. If she is below or heading down she is negative. She starts 2 feet above which is 2. She descends a total of -9 from 2 to -7. She ends up -7 or 7 feet below surface. So she travels from 2+-9 = -7.
Yolanda owes her friend $15 or -15. She earns $8 a week or +8. If she earns 8 dollars this week and pays Yolanda back then -15+8=-7. She now owes $7.
