Answer:
118°
Step-by-step explanation:
EDC is 31° and ECD has the same measure. (Triangle DEC is isosceles)
The total sum of angle EDC and ECD is 31 + 31 = 62°
The total sum of all the angle measures in a triangle is 180°, so just subtract 62 from 180 to get the measure of angle DEC.
180 - 62 = 118°

=11(270x2+1)
Answer:
11(270x2+1)
this is the answer of the equation as a graph
Answer:
The origin is at (0,0) its where the x and y coordinate intersect.
Step-by-step explanation:
what was the question here?
Sum of all interior angles = (n-2)x180, n being the number of sides.
sum of all interior angles = (n-2)x180
sum of all interior angles = (14-2)x180
sum of all interior angles = 12 x180
sum of all interior angles = 2160°
