Where would an imaginary line need to be drawn to reflect across an axis of symmetry so that a regular pentagon can carry onto i
oksano4ka [1.4K]

The <em><u>correct answer</u></em> is:

A line of reflection would need to be drawn as a line that bisects a vertex angle of the pentagon.

Explanation:

A line that bisects a vertex angle of a pentagon will be a line of symmetry within the pentagon. The pentagon can be "folded" through this line into two equal halves.

This imaginary line represents the center of the pentagon. A reflection through this line will carry the pentagon onto itself. This is due to the definition of line symmetry:

"A set of points has line symmetry if and only if there is a line, l, such that the reflection through l of each point in the set is also a point in the set."

Additionally, for any regular polygon, the number of lines of symmetry equals the number of sides.

This means that this line can be through any vertex angle of the polygon.

OleMash [197]
Given that a<span> passenger elevator in the sears tower in Chicago can lift people 960 feet in 1 minute and 30 seconds (1.5 minutes). This means that the lift is travelling with a speed of:

</span>speed= \frac{distance}{time} = \frac{960}{1.5} =640ft/min
<span>
If the elevator lifts cargo through the same height in 2 minutes and 30 seconds (2.5 minutes), then the speed is given by:

</span>speed= \frac{960}{2.5} =384ft/min<span>
</span>
