Answer:
x = 10°
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°
