A triangle has two sides with lengths 7m and 12 m. Which of the following lengths could represent the length of the third side?
Choose all that apply.

A) 4m
B) 7m
C) 10m
D) 17m
E) 19m

E 19m 7m+12m=19m

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.

what i would say the best answer is a. 40.5
