Answer:
106
Step-by-step explanation:
If you find the sum of the interior angles, you can determine the supplement to z.
Then all you have to do to get z is to subtract it from 180.
Method
The supplement of 72 is 180 - 72 = 108
The supplement of 51 is 180 - 51 = 129
The supplement of 60 is 180 - 60 = 120
The supplement of 71 is 180 - 71 = 109
Let y = the supplement of z
y + 108 + 129 + 120 + 109 = 540
y + 466 = 540
y = 540 - 466
y = 74
z + y = 180
z + 74 = 180
z = 180 - 74
z = 106

Answer:
The factored difference is: 
Step-by-step explanation:
Difference in non factored form:
To find the difference in non-factored form, we subtract the common terms. So

Greatest common factor:
Of the exponents: Between
and
, it is the one with the lowest exponent, so x.
Between 14, 20 and 10:
14 - 20 - 10|2
7 - 10 - 5
So 2
The gcf is 2x, which means that the factored expression is:

The factored difference is: 
Answer:
Median: 0.5
Step-by-step explanation:
Arrange the following set of data from least to greatest:
0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.9
then find the middle number (the median).
since there are seven numbers in the data set we divide it, by doing this:
{0.2, 0.3, 0.4} 0.5 {0.6, 0.7 0.9}
Therefore, the median for the data set is 0.5!

Answer:
Hi there!
The answer to this question is c=23, b and d=157
this is because c is the vertical angle of a meaning the values are equal
and b is the supplementary angle to a: all you do is subtract 23 from 180 to get 157.
b is vertical to d, so d is also 157
ok about this exercise, we need the square meters measured by the entire stand to do the calculations, because the statement only gives the square meters that are painted with a paint can
