Use a proportion to find the unknown side of the similar figure.

x =

34 cm

6.25 cm

36 cm

Step-by-step explanation: 4 times 2.4 gives you 9.6. So you do the same to the 15. 15 times 2.4 = 36.375, or just 36.

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.

you'll have to attache the image of the bar graph in order for us to answer : )
