Question

Solve for x, in the picture below

Answer 1

x = 45

Explanation:

CDE + CDE + CED =180°

x + 2x + 45 = 180

3x = 135

x = 45

Answer 2

Given:

angle CED = 45°

angle EDC = x

angle DCE = 2x

To Find:

The value of x.

Angle Sum Property:

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

Solution:

x + 2x + 45° = 180°

or, 3x = 180° - 45°

or, 3x = 135°

or, x = 135/3 = 45°

Answer:

The value of x is 45°.
