Answer:
∠STU = 69°
Step-by-step explanation:
The angle with vertex T is called an "inscribed angle." It intercepts arc SU. The relationship you are asked to remember is that the measure of the inscribed angle (T) is half the measure of the arc SU.
Point V is taken to be the center of the circle. The angle with vertex V is called a "central angle." It also intercepts arc SU. The relationship you are asked to remember is that the measure of the central angle (V) is equal to the measure of arc SU.
__
Using these two relationships together, we realize angle V is twice the measure of angle T:
∠SVU = 2×∠STU
18x +12° = 2(18x -57°) . . . . . . relationship between the marked angles
18x +12° = 36x -114° . . . . . eliminate parentheses
126° = 18x . . . . . . . . . . . add 114°-18x
∠STU = 18x -57° = 126° -57°
∠STU = 69°

<em>Additional comment</em>
You may notice we did not solve for x. We only needed to know the value of 18x, so we stopped when we found that value. (Actually, we only need the value of 18x-57°. See below.)
__
<em>Alternate solution</em>:
(18x +12°) -(18x -57°) = 18x -57° . . . . . . . subtract 18x -57° from both sides of the first equation.
69° = 18x -57° . . . . . simplify. This is the answer to the problem.
Answer:

Step-by-step explanation:
Since the line goes through the origin and is propotinal, we just do y/x
4/3= 1 1/3
y=1 1/3x

Answer:
the answer is 21.Here is how I know
Alright, lets get started.
The base price is given : $ 24990
The dealer pays 76% of the base price means
he pays for base price :
he pays for base price : $ 18992.4
For options, total : 
He pays 88% for options, means
he pays for options : 
he pays for options : $ 2270.4
So, total dealer pays :
destination charges
So, total dealer pays :
$ 21892.8
Hence dealer's cost : $ 21892.8
Price of sticker will be : 
Price of sticker will be : $ 28200
dealer's cost : $ 21892.8
Hope it will help :)
