Could someone help me please? You could do the ones you know, and try to explain.

I only know the answer to B which is 50*

Step-by-step explanation:

B is 50* because there are 3 vertical lines therefore the angle opposite of 80* is also 80* so when we add them together, we can take 160* out of the 360* whole. so now we are left with 200* which are 2 sets of vertical lines and one of each of the vertical lines are x therefore the remaining angles are equal so all I have to do is divided 200* by 4 which is 50 therefore x is equal to 50*.

PS: the * sign is supposed to be the degree sign but I don't have it on the keyboard so just act as if it was the degree sign lol

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
