Answer:
6
Step-by-step explanation:
You can memorize these for the smaller shapes
for equilateral polygons:
triangle: 60
square: 90
pentagon: 108
hexagon: 120
Otherwise, I believe the formula is the total degrees in a polygon (s-2)*180 where s is the number of sides.
So the measure of each angle on average would be (s-2)*180/s.
There (s-2)*180/s = 120
180(s-2) = 120s
180s-360 = 120s
60s = 360
s = 6
Answer:
(2,-2)
Step-by-step explanation:
The solution to a system of equations like these, is where the two lines intersect. In this case, I believe, it would be at point (2,-2). Although, it is a little hard to pinpoint without the labeled number lines.
Hope this helps! Best of luck!

Answer:
The length of the long piece is 33 meter.
Step-by-step explanation:
Given : For their homecoming parade, the students of U-Math have created a colorful banner, 43 meters in length, that is made of two pieces of parachute material. The short price is 23 meters shorter than the long piece.
To find : The length of each piece ?
Solution :
Let the length of the longer piece be 'x'
and the length of the shorter piece be 'y'
Total length is 43 meters.
So, ...(1)
The short price is 23 meters shorter than the long piece.
i.e. ...(2)
Solving (1) and (2) by adding (1) and (2),
Substitute in (1),
The length of the short piece is 10 meter.
The length of the long piece is 33 meter.
