Answer:
Step-by-step explanation:
For a polygon of N sides, the sum is
N*(180-360/N) = N*180 - 360 degrees
Subtract (120 +93 +108 +101) from 540 for your answer
Angles EBC and EDC are the same. and straight lines equal 180
so now to solve for x
100 it's like the absolute value
The straight line graph is the one that shows a direct, proportional relationship.
