What is the degree measure of the smaller of the 2 angles
What is the degree measure of the smaller of the 2 angles formed by the line and the ray shown in the figure below?
- 14°
- 28°
- 29°
- 58°
- Cannot be determined from the given information
Answer
The correct answer is D.
Because the base is a straight line, these two angle measures add up to 180°.
(4x + 6) + (2x) = 180
6x + 6 = 180
x + 1 = 30
x = 29
This makes one angle measure 4(29) + 6 = 122 degrees and the other angle measure 2(29) = 58 degrees.
