Answer:
c) 27°
Explanation:
Step 1: Find the value of x
All angles on a straight line are equal to 180 degrees.
Therefore,
60 + 2x + (2x+12) = 180
72 + 4x = 180
4x = 108
x = 27°
Step 2: Through the value of x, calculate all angles
2x = 27 (2) = 54°
2x + 12 = 2 (27) + 12 = 66°
x + 2 = 27 + 2 = 29°
27° is not a measure of an angle in the figure.
Therefore, option c is the correct answer.
