<h3>Given:</h3>

angle CED = 45°

angle EDC = x

angle DCE = 2x

The value of x.

<h3>Angle Sum Property:</h3>

The sum of all the Interior Angles of a triangle is 180°.

<h3>Solution:</h3>

x + 2x + 45° = 180°

or, 3x = 180° - 45°

or, 3x = 135°

or, x = 135/3 = 45°

<h2>Answer:</h2>

The value of x is 45°.

Airida [17]

A segment is created from points A and B. To copy segment AB,"The distance between points A and B" needs to be identified for the construction

This is further explained below.

<h3>What is a segment?</h3>

Generally, In this case, we have two points A and B, which form a segment. The production of a carbon duplicate of segment AB requires the determination of "The distance between points A and B."

In conclusion, In this case, we have two points A and B, which form a segment. The production of a carbon duplicate of segment AB requires the determination of "The distance between points A and B."
