Because n is a variable and a variable is serving that you can always change.
My guy, the answer would be 192 ft^2 hope this helps, plz give brainliest.
Answer:Line E
Step-by-step explanation:
The equation is in the form of y=mx+b. M stands for slope and b is y-intercept. The y intercept is 4 and the only one with a positive y intercept is Line E. To check our answer we can see that the slope is positive which means the line is ascending(eliminating line t) and is greater than 1 which means that it is steeper than the line y=x(eliminating line p)
If two angles are supplementary, then they add up to 180.
Angle 1 = twenty less than four times the other angle
Angle 2 = the other angle
Angle 2 = 1x
Angle 1 = 4x - 20
Next, we can add up angles 1 and 2 and set the sum equal to 180.
x + 4x - 20 = 180
5x - 20 = 180
5x = 200
x = 40
Now that we know x, we can find the values of our angles.
Angle 1 = 4(40) - 20 = 160 - 20 = 140 degrees
Angle 2 = 40 degrees
Hope this helps!! :)
