The manager already hired 9 people. Let 
be the number of people he still can hire. Since these people will add to the 9 he already hired, when the hiring campaign will be over he will have hired 
people. We know that he can't hire more than 14 people, so the number of people hired must be less than or equal to 14:
If we subtract 9 from both sides, we have
so, the manager can hire at most 5 other people
Answer:
X = 100
Y= 140
Step-by-step explanation:
The angle of y is same with 140, x u just need to 180= 2(180-140)+x

The graphed cosine function can either be:
cos(x + pi) or cos(x - pi).
<h3>
Which is the equation of the graphed function?</h3>
We know that this function is a cosine function with a phase shift, so the general form is:
f(x) = cos(x + P).
Where P is the phase shift.
In the graph we can see that when x = 0, f(0) = -1
And we know that cos(pi) = -1 = cos(-pi)
Then we must have that:
f(0) = cos(P) = -1
By what we wrote above, we know that P can be either -pi or pi (because of the parity of the cosine). Let's say that P = pi, then the cosine function is:
f(x) = cos(x + pi).

Answer:
Step-by-step explanation:
Triangle ABC is right triangle. Since m∠ACB = 90° and m∠ACD = 60°, you get m∠BCD = 90°-60°=30°.
Triangle BCD is rigth triangle, then the leg that is opposite to the angle of 30° is half of the hypotenuse. Thus,
By the Pythagorean theorem,
Then
Hypotenuse AB of the triangle ABC is equal to
The area of the triangle ABC is
