Answer:
octagon, a regular polygon and convex
Step-by-step explanation:
The given shape has eight sides and all these shapes do not intersect each other, thus by the definition of polygons, the polygon which consists of eight sides is known as "octagon".
Also, A regular polygon is the polygon which has same sides and same angles and also the sides do not intersect each other.
Hence, the given shape is a regular polygon and also, the regular polygons are convex in nature.
Therefore, the given shape is octagon, a regular polygon and convex in nature.
Answer:
C) 28.26 ft²
Step-by-step explanation:
2x-13+3x-8+2x-3+2x-7+3x-1+2x+11+2x+9= (7-2)×180
16x-12=(7-2)×180
(7-2)×180 Work this out on a calculator
And then that answer=16x-12
Then you solve by adding 12 both sides and dividing by 16 both sides to get what x is.
