Answer:
x=141
Step-by-step explanation:
(n-2)•180 = Sum of all the interior angles
n = # of sides
(7-2)•180
5•180
900= Sum of all the interior angles
Add all the angles and equal them to 900
125+122+131+x+7+x+107+x-15=900
Add all the numbers up first on the left side
477+3x=900
3x=423
x=141
Answer:
X = 6 1/2

Answer:
(3, -2) and (9, 0)
Step-by-step explanation:
x-3(-2)=9
x+6= 9
x=3
9-3y=9
-3y=0
y=0
Name them as vertices A,B,C , D and E in that order.
