Angles D and F are supplementary, so
.. (19x -26) +(7x -2) = 180
.. 26x = 208
.. x = 208/26 = 8
∠EFG = (7x -2)° = (7*8 -2)° = 54°
Selection C is appropriate.
Answer: Every polygon that is not a triabgle (3 vertices), quadrilateral (4 vertices) or pentagon (5 vertices) has more than 5 vertices. So it would be a hexagon, heptagon, etc.
I think answer is B.I am not sure because I found purple it is 1.350 but I found the yellow is 240 and it is more close to 420.I telling you I am not sure but this is my opininon.
Do you need the expanded notation form, or expanded factor form?
A=3
B=4
C=5
Substitute 3 in for 'a' in the equation, and 5 in for 'c' in the equation to get 17.
