1.Given a∥b , and c is not parallel to a or b, which statements must be true?Select each correct answer.m∠7=m∠11m∠5=m∠12m∠4=m∠5m∠1=m∠52.In the figure, AB¯¯¯¯¯∥CD¯¯¯¯¯ and m∠4=85°.What is m∠5?Enter your answer in the box.
Accepted Solution
A:
1. is m∠4=m∠5 by the alternate interior angle theorem. 2. Angles 4 & 3 are supplementary angles or linear pair and so they have to equal 180 and 180 - 85= 95 3 & 5 are corresponding angles so 95 should be your answer.
