Example Question #11 :Geometry

If,, and, what is the measure, in degrees, of?

Alternate interior angles

Possible Answers:

148

58

122

62

32

Correct answer:

148

Explanation:

The question states that. The alternate interior angle theorem states that if two parallel lines are cut by a transversal, then pairs of alternate interior angles are congruent; therefore, we know the following measure:

The sum of angles of a triangle is equal to 180 degrees. The question states that; therefore we know the following measure:

Use this information to solve for the missing angle:

The degree measure of a straight line is 180 degrees; therefore, we can write the following equation:

The measure ofis 148 degrees.
