Answer:

x = 10°

Step-by-step explanation:

m∠DCR is an exterior angle of the triangle DCE

Solving For Exterior Angles:

To find the value of an exterior angle, we must sum up the two opposite (corresponding) angles inside the triangle

In this case, 2x + 7 and 26 are the corresponding angles

Solve:

6x - 7 = 2x + 7 + 26

4x - 7 = 7 + 26

4x = 14 + 26

4x = 40

x = 10°

Your answer : x = 10°
