Answer:

∠ XMZ = 74°

Step-by-step explanation:

Since the corresponding arcs on the 2 circles are congruent , then the central angles are congruent, that is

6x - 88 = 3x - 7 ( subtract 3x from both sides )

3x - 88 = - 7 ( add 88 to both sides )

3x = 81 ( divide both sides by 3 )

x = 27

Then

∠ XMZ = 3x - 7 = 3(27) - 7 = 81 - 7 = 74°

Is this a<br> function?<br> Why or why not? Ty

AleksAgata [21]

Answer:

No, because there isn't a pattern in the numbers. For the y you are adding one but for the x there isn't a shown pattern. Also when graphing the table, it doesn't make a straight line.

Step-by-step explanation:

For example, look at the table shown. On the x you are adding 1 and for the y you are adding 2. This makes it a function and creates a straight line
