Step-by-step explanation:
Inscribed Angle Theorem
If an angle is inscribed in a circle, then the measure of the angle equals one half the measure of its intercepted arc.
so the intercepted arc is TWICE the measure of an angle inscribed in a circle
1. A central angle is an angle with endpoints located on a circle's circumference and vertex located at the circle's center. A central angle in a circle determines an arc.
2. An inscribed angle is an angle formed by three points on the circle's circumference.
Angle at the Center Theorem: An inscribed angle is half of the central angle (if they determine the same arc).
In your case angles:
1. ∠QSR is insribed (determines the arc QR);
2. ∠QTR is central (determines the arc QR).
Then by Angle at the Center Theorem, m∠QTR=2m∠QSR=2·52°=104°. Arc QR has the same measure as central angle QSR.

Answer:
Use all the given information:
<em>Price of a slice in $ -</em><em> x</em>
<em>Number of slices- </em><em>3</em>
<em>Total cost of slices-</em><em> 3x</em>
<em />
<em>Price of chopped cheese in $- </em><em> 2+x</em>
<em>Number of chopped cheeses-</em><em> 4</em>
<em>Total cost of chopped cheeses-</em><em> 8+4x</em>
<em />
<em>Total cost- </em><em>7x+8</em>
<em />
Step-by-step explanation:
We are told that the price of a slice is x and that Dashaun bought 3 slices.
So to find the total amount paid for slices, multiply the price by the number of slices:
We are told that the price of chopped cheese is $2 more than a slice. Use y as the cost for chopped cheese:
Dashaun bought 4 chopped cheeses.
To find the total cost of chopped cheeses bought, multiply the cost per cheese by the amount of cheese purchased:
Insert the value of y:
Use the distributive property:
This is the total cost for the chopped cheeses.
To find the total of lunch, add the prices for the slices and cheeses together:
The total cost for lunch is <em>7x+8</em>
