Bentley wants to determine the height of a tree. He is 5 and 1/2 feet tall.
and his shadow is 8 feet long. At the same time, the tree's shadow is
15 feet long. To the nearest tenth of a foot, what is the height of the
tree?
a 3 ft
c. 103 ft
b. 7.5 ft
d. 17.5 ft

10.3 ft

Step-by-step explanation:

5.5/8 = x/15

multiply by 15

x=10.3 ft

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.
