C) 65
The lines mean that they are equal or same congruent whatever. Since the top angle is 50 we can subtract 50 from 180.
180 - 50 = 130
Now the other Angles are equal so divide 130 by 2 and you get 65.
I don’t understand please put it in a form i could possibly understand

Let's think of something that one can hold against a page and draw a circle. Some examples are: a cup, a D battery, a can of soda, the tube from the inside of a paper towel roll, a can of beans, etc.
Think of the can of beans. The part that touches the page (and that you trace around with your pencil) is called a face.What these items have in common is that the faces at the ends are circles (they may or may not be the same size).
The name for this 3-D figure is called a cylinder. Her block, therefore, is a cylinder.
Technically, if the ends were ovals we would still call it a cylinder and so to make sure you have the one with the circles at the ends you would say you have a "right circular cylinder" but for most cases people just say "cylinder" and assume the ends are circles. It really depends what level (elementary, middle school, hs, college) of math you are doing whether just cylinder suffices.
Answer:
z is 111 degrees
Step-by-step explanation:
69 ° and z is a linear pair, therefore:
69 + z = 180
z = 180 - 69
z= 111
