Another method to get the lentgth of two sides:
By looking at the coordinates you can see that (-5,2) and (7,2) gives one side, which is 12 long (the length from -5 to 7) and (7,2), (7,-3) gives another side, which has a length of 5 (from 2 to -3). Use the Pythagorean theorem to get the last side:
5^2 + 12^2 = x^2
25 + 144 = x^2
169 = x^2
13 = x
You need the perimeter so simply add all the sides together: 12+5+13= 30

So the answers are:
1) point w=80, vertically opposite
2) 95+120+85+d=360
D=360-300
Point D= 60
3)65+87+110+G=360
G= 360-262
Point G=98
4) point L=90, the square is super easy
5) point L= 68
6) 90+86+114+V=360
V=360-290
Point V=70

10 people who build at the same rate can frame a house in 6 days. That means it will take one person days to finish the house.
Which means that it will take 4 people days to finish the house.
So, the fractional part of the house 4 people can frame in 3 days will be
Thus, OptionD is the correct answer.

Answer:
140 deg
Step-by-step explanation:
The sum of the measures of the interior angles of an n-gon is
(n - 2)180
In a 9-gon, there are 9 sides, so n = 9.
The sum of the measures of the interior angles of a 9-gon is
(n - 2)180 =
= (9 - 2)(180)
= 7(180)
= 1260
A regular polygon has congruent interior angles. A 9-gon has 9 congruent interior angles. The measure of each interior angle is the sum of the measures of the interior angles divided by the number of angles.
1260/9 = 140

When a subtraction problem is performed, the answer is the difference between the two numbers being subtracted.
What is subtraction
Subtraction is the mathematical operation of finding the result when one quantity is taken away from another.
For example, if you have the subtraction problem 7 - 3, the answer would be 4, as you are subtracting 3 from 7, resulting in a difference of 4.
Similarly, in the subtraction problem 15 - 8, the answer would be 7, as you are subtracting 8 from 15, resulting in a difference of 7.
In general, when performing a subtraction problem, you are finding the numerical difference between two values.
