Find all missing angles in the diagrams below, please help

x = 80,

y = 80

Step-by-step explanation:

This is difficult to explain, so here are the theorems used

two lines parallel, with a transversal; alternate interior angles,

verticle angles theorem,

parts - whole postulate,

verticle angles theorem,

parts- whole postulate,

sum angles in a triangle,

supplementary angle, definition straight angle,

parts- whole postulate,

there are many other ways to reach the answer, I just whent this way.

x= 80°, y= 100°

Step-by-step explanation:

Please see the attached picture for the full solution.

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
