Find the missing angles in each of the following:
Need to show an attempt of these problems. What is the difficulty here?
Triangle: 180-129= 51
A= 180-51-42= 87 degrees
Regular Octagon: (8-2)180/8= 135 degrees
I am not sure how to find the angles for the other problems
Are you familiar with this theorem?
You can use this for the top right and bottom right problem in your attachment.
Are you also familiar with supplementary angles?
a is corresponding to y
z is the alternate exterior angle to a
x is supplementary to a
< 3= 80
I am not sure how to solve for < E and < A
You were also given three pairs of parallel lines. Use that, and the theorem I quoted in post #5, to find angles E and A.
