Answer:
x=6, y=75
Step-by-step explanation:
Since the diameter of the circle is a perpendicular bisector to the chord, x and 6 must be equal and therefore x=6. It also bisects the arc, meaning that y=75. Hope this helps!

Step-by-step explanation:
for the 2 lines to be parallel the angles of crossing the third line must be equal.
and it is a given for 2 crossing lines, that the right top angle is equal to the left bottom angle, and the left top angle is equal to the right bottom angle.
therefore, the 2 indicated angles must be equal :
3x + 48 = 6x
48 = 3x
x = 16
64, 68, 71, 87, 215, 215
To find the median, we must find put the data set in order from least to greatest.
Great! We already have it like that :)
Now, our median is in between 71 and 87
So, basically, we have to find what the median of 71 and 87 are.
Simply add the two numbers together, and then divide it by 2.
71 + 87 = 158
158 ÷ 2 = 79
So, 79 is your median!
