Given a regular decagon, find the measures of the angles formed by (
Sonja [21]
A decagon has 10 sides (think decade and decathlon). From the center of the decagon we draw the radii and in doing so we take the area of the decagon and divide it into 10 congruent Triangles.

The angles around the center add up to 360 because they form a circle and since there are 10, they each measure 36 degrees. So the answer to the first part (the angle between the radii) is 36 degrees.

Each of these triangles has two equal sides (both radii) so is Isosceles. That means that the base angles are congruent. So the two angles that are left in each triangle must measure the same. Since the angles in a triangle add up to 180 degrees, we know that the two remaining angles are together equal to 180-36=144 degrees. Since they are equal in measure they each measure 72 degrees.

Thus the answer to the second part, trhe measure of the angle between a radius and the side of the polygon is 72 degrees.

Find the volume of a rectangular prism with dimensions 21 in. by 20 in. by 19 in., to the nearest hundredth cubic foot
Maurinko [17]

Answer:

The dimensions of a rectangular prism are 21 in. by 20 in. by 19 in.

To find:

The volume of the rectangular prism.

Solution:

Let the length, breadth and height are 21 in, 20 in and 19 in respectively.

Volume of the rectangular prism is

V=Length\times Breadth\times Height

V=21\times 20\times 19

V=7980

Therefore, the volume of the rectangular prism is 7980 cubic inches.

A farm grows both beans and corn. Each year, beans earn $900 per acre and corn earns $600 per acre. The farm has a total of 58 a
beks73 [17]

Answer:

35 acres of beans and 23 acres of corn

Step-by-step explanation:

58 divided by 2 = 29 +8 = 35 x 900 = 31500

                          = 29 - 6 = 23 x 600 = 13800

                                                            = 45300
