Answer:
A. 37.5°
Step-by-step explanation:
∠SPT can be considered an inscribed angle in the circumcircle. In that circle, arc ST would have a measure of 360°/8 = 45°. Angle y° is half that measure, so is 22.5°.
The external angles of a regular octagon are 360°/8 = 45°, so that is the measure of angles UTW and UVW. It is also the amount by which reflex angle TUV exceeds 180°.
The sum of the interior angles of quadrilateral TUVW is ...
45° +225° +45° +3x° = 360°
Then 3x° = 45° and x° = 15°.
Then the sum of interest is ...
x° + y° = 15° + 22.5° = 37.5°

Answer:
A. and D.
Step-by-step explanation:
To get the unit rate, you divide the y value by the x value.
180/15 = 12
The x value becomes a 1.
This means A. is correct.
Take the unit rate to find the profit for 20 scarves. To get 20, you multiply 1 by 20.
1 * 20 = 20
Do the same to 12.
12 * 20 = 240
This will give you the point (20, 240).
This means D. is correct.
