Answer:
x=10
Step-by-step explanation:
The 3 angles of a triangle add to 180
4x+60+80 = 180
Combine like terms
4x+140 =180
Subtract 140 from each side
4x+140-140=180-140
4x = 40
Divide by 4
4x/4 = 40/4
x = 10

Answer:
The dependent variable is A
The independent variable is w
Step-by-step explanation:
Given

Required
Identify the variables
In 
The value of w is independent of the value of A.
In other words:
A derive its own value from w; by multiplying 25 and w.
Take for instance:

The value of A would be:


Hence:
The dependent variable is A
The independent variable is w
