I WILL GIVE BRAINLY! The surface of a table to be built will be in the shape shown below. The distance from the center of the sh

ape to the center of each side is 8.7 inches and the length of each side is 10 inches. A hexagon labeled ABCDEF is shown will all 6 sides equal in length. ED is labeled as 10 inches. A perpendicular is drawn from the center of the hexagon to the side ED. This perpendicular is labeled as 8.7 inches. Part A: Describe how you can decompose this shape into triangles. (2 points) Part B: What would be the area of each triangle? (5 points) Part C: Using your answers above, determine the area of the table's surface. (3 points)

Answer:draw lines center to vertex

43.5 square inches

261 square inches

Step-by-step explanation:

Part A:

The area can be decomposed into triangles by drawing a line from the center to each vertex of the hexagon.

__

Part B:

The area of each triangle is given by the triangle area formula:

 A = (1/2)bh

 A = (1/2)(10 in)(8.7 in) = 43.5 in²

__

Part C:

The area of the table top is 6 times the area of one triangle:

 surface area = 6(43.5 in²) = 261 in²

Find K' if the figure is reflected across the x-axis
snow_lady [41]
<h3>Answer:  K ' is at (1, 4)</h3>

Explanation:

Point K is located at (1, -4)

We use the rule that (x,y) \to (x,-y) when reflecting over the x axis.

The x coordinate stays the same, but the y coordinate flips from positive to negative or vice versa.

Therefore, K(1,-4) will move to K ' (1, 4)

What's 2x+3y=6 and x-3y=9?
Vedmedyk [2.9K]
Set up a system of equations:

2x+3y=6
x-3y=9

You can solve this with elimination by adding the two equations together:

3x+0y = 15
3x=15
x=5

Then, plug this value back into either of the original equations to find the y value:

5-3y=9
-3y=4
y= -4/3

The point of intersection is (5,-4/3)
