-
Step-by-step explanation:
We are given
total number of guests called for room services =170
total number of guests did not called for room services =255
now, we can find total number of guests
Total number of guests =(total number of guests called for room services)+(total number of guests did not called for room services)
so,
total number of guests is
=170+255
=425
now, we can find percentage
percentage of the guests at this hotel called for room service yesterday is %40
So,
The percentage of the guests at this hotel called for room service yesterday is 40%
we are given inequalities as
Subtract both sides by 1
so, we get interval as
![(-\infty,-4]](https://tex.z-dn.net/?f=%28-%5Cinfty%2C-4%5D)
we have
we can divide both sides by -4
so, we get interval as
now, we can combine them
∪
now, we can draw number line and locate this interval
we get
Let 1 angles be x, then its supplement is 180-x
x+x+12=180
2x=168
x=84
angles are 84 and 96
That would be B.
The set of points are all on the line which is a bisector.
