Question

6)A pair of parallel lines is cut by a transversal: A pair of parallel lines cut by a transversal is shown. The inside bottom right angle is labeled 80 degrees. The alternate interior angle is cut by a ray and is labeled as x on one side and 15 degrees on the other. What is the measure of angle x?

Answer 1

If you draw it out, you'll notice that 15+x= 90 because they are alternate interior, meaning they are the same. X is the missing value needed to be added to equal 90. Therefore. your answer is 75 because 75+15=90.
