Answer:
Equation: 900=139+(-x+167)+(-2x+194)+(-3x+202)+(-x+183)+(142)+(-x+169)
x=37
Step-by-step explanation:
This is a 7 sided polygon
Those are exterior angles
900 degrees= 7 sided polygon
So to find x
look interior plus exterior = 180
180-41=139
180-(x+13)=−x+167
180-(2x-14)=−2x+194
180-(3x-22)=−3x+202
180-(x-3)=−x+183
180-(38)=142
180-(x+11)=−x+169
now add them all up equal to 900
900=139+(-x+167)+(-2x+194)+(-3x+202)+(-x+183)+(142)+(-x+169)
just simplify all that
and combine like terms
x=37
