Mathematics
1 answer:
Makovka662 [10]3 years ago
4 0

Answer:

x = 11

Step-by-step explanation:

distribute: 4x - 28 = 27 - x

add x to both sides: 5x - 28 = 27

add 28 to both sides: 5x = 55

divide 5 to both sides: x = 11

Write cos11π18 in terms of the cosine of a positive acute angle.
NNADVOKAT [17]

You have to use the fact that \cos(\pi-x)=-\cos x for any value of x. So

\cos\dfrac{11\pi}{18}=-\cos\left(\pi-\dfrac{11\pi}{18}\right)=-\cos\dfrac{7\pi}{18}

where \dfrac{7\pi}{18} is the positive acute angle you're looking for.

How do I find the domain?
chubhunter [2.5K]
Domain is the set of numbers you can use for the equaiton

remember you can't divide by zero, or take the squaer root of a negtive number (we don't have sqrts in this quesiton so don't worry about last one)

so you can't divide by 0
domain =all real number except those that make divide by zero

where is that?
x-1=0
x=1

when x=1, we can't allw that

domain=all real numbers except 1
