The answer is the option B, which is: B. Similar hexagons.

The explanation for this answer is shown below:

By definition, a cross section is the shape that is formed when a plane cuts or makes a slice through a solid.

The hexagonal pyramid has an hexagonal as its base. If you make slices parallel to the base of this pyramid, you will see the shape of this base in different sizes. Therefore the shapes that are formed by cross sections parallel to the base of the hexagonal pyramid are similar hexagons.

Bezzdna [24]

Answer:

12.58 feet.

Step-by-step explanation:

Ron wants to build a 14 ft. ramp with an angle of the rise of 26° and the height of the ramp is about 6.1 ft.

We have to find out the length of the base of the ramp.

Now, the ramp forms a right triangle with the base and the height and here, the hypotenuse of the triangle is the ramp itself i.e. 14 ft.

If the base length is x feet, then we can write using the trigonometry

$\cos 26^{\circ} = \frac{\textrm{Base}}{\textrm {Hypotenuse}} = \frac{x}{14}$

⇒ x = 14 cos 26° = 12.58 feet. (Answer)

10 - 2x = 19x +2 - 5x

Darina [25.2K]

Answer:

x = 1/2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

10−2x=19x+2−5x

10+−2x=19x+2+−5x

−2x+10=(19x+−5x)+(2)(Combine Like Terms)

−2x+10=14x+2

Step 2: Subtract 14x from both sides.

−2x+10−14x=14x+2−14x

−16x+10=2

Step 3: Subtract 10 from both sides.

−16x+10−10=2−10

−16x=−8

Step 4: Divide both sides by -16.

−16x/−16 = −8/−16

x = 1/2
