Answer:
-12°
Step-by-step explanation:
it is negative because it it below zero.
If this is a 100-gon, then not only does it have 100 sides, it also has 100 central angles. Each one measures 360/100 = 3.6. This is the vertex angle for each of those 100 triangles. 180 - 3.6 = 176.4, which has to be split equally between the 2 base angles. This puts each of those at 88.2. If you are looking for the exterior angle to each of those, it's the supplement of them. 180-88.2 = 91.8
Here we are given the expression:

Now let us equate it to zero to find x first,

Now subtracting 18 from the other side,

taking square root on both sides,
So we will get two values of x as ,


Now we can write square root -1 as i,
So our factors become,


Answer:
The final factored form becomes,

Step-by-step explanation:
distance between (12.-7) and (-3, -7)

=12+3
=15 units
Answer:
mean absolute deviation is <em>8</em>
Step-by-step explanation:
to find mean absolute deviation, you subtract your mean from each of your values, and make them all positive, (even if u get a negative..)
then you add all your new answers up and divide by how many numbers there are (basically just find mean of your new set of data...)
