PLEASE I REALLY NEED HELPA wooden block in the shape of a rectangular pyramid is shown below:
If a cross section of the block is cut perpendicular to the base and passes through the top vertex of the pyramid, which of the following shapes describes the cross section?

Triangle
Rectangle
Trapezoid
Hexagon

Answers

I've attached an image that might help you visualize it! The cross section is outlined in red. It's perpendicular to the base (so it's completely vertical) and passes straight through the middle of the pyramid.

The green dashed line is the shape of the cross section. It is a triangle because that side of the pyramid will have three sides when cut through the middle.

Answer:

The answer is a triangle.

Find the distance (-4,5) and (7,18)

Answers

Answer:

$√(290)\ units$

Step-by-step explanation:

The distance between points $(x_1,y_1)$ and $(x_2,y_2)$ is

$√((x_1-x_2)^2+(y_1-y_2)^2)$

Hence, the distance between points $(-4,5)$ and $(7,18)$ is

$√((-4-7)^2+(5-18)^2)\n \n=√((-11)^2+(-13)^2)\n \n=√(121+169)\n \n=√(290)\ units$
