10. (07.01 LC) The figure below shows a triangular piece of cloth:

What is the length of the portion BC of the cloth? (5 points)
O 5 cos 38°
O cos 38
5
sin38
5
O
5 sin 38°

the answer is a

step-by-step explanation:

because your just changing the position of where the shape is

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.
