Answer:
sum of interior angle of heptagon is 900°.
140°+148°+136°+150°+142°+90°+x=900°
806+x=900°
x=900°-806°
x=94°
Answer:
slope = 
Step-by-step explanation:
Use the slope formula given in the question to solve for the slope. The 
is the variable representing the slope. The 
and 
values are x and y values of one point. The 
and 
are x and y values of another point.
So, use the x and y values of the points given and substitute them in the correct order into the formula:
Thus, the slope is .
If order doesn't matter then the number of possible choices is:
Answer:
The answer to your question is: 111°
Step-by-step explanation:
The sum of the interior angles of a polygon is (n - 2) 180°
This polygon has 7 sides
Then n = 7
Process
120 + 158 + 126 + 125 + 121 + 139 + x = (7 - 2)180
120 + 158 + 126 + 125 + 121 + 139 + x = 5(180)
789 + x = 900
x = 900 -789
x = 111°
Since U is a universal set where S is its subset, then set U should consist of all the letters, numbers and punctuation mark in a keyboard. In other words, universal set U consists of the following elements:
U = (0, 1, 2, 3, 4, 5, 6, 7, 8, 9)
U = (x| x comprised of all the letters in the alphabet fro a to z)
U = (!,.,,,?,!:,;,",',-)
