Answer:
x=120
y=60
Step-by-step explanation:
So it states that this is an equilateral triangle which means that all of the angles in this triangle or the same
the sum of all the angles is equal to 180 so to find y we divide 180 by 3
180/3=60
y=60
we notice that its supplementary to the angle that measures 60 and supplementary angles add up to equal 180 so to find x we subtract 60 from 180
180-60=120
x=120
Ok now this one i am 100% confident in my answer
You could do this with two weighings assuming its a two pan balance - (1) place three balls on each side - if they balance out then its the remaining three that has abnormal ball (2) out of that group, place one ball on each side - if balances it out, the abnormal ball is the remaining one.
If the weighing in step (1) does not balance out, grab the group of three balls that is light or heavy and repeat step (2) described above.

Step-by-step explanation:
Im pretty sure im right
Y=2x, rise/run. start from 0,0, go up the y axis until you see that the line hits a solid point which is 1,2.
