Step-by-step explanation:
2 [ { 2 - 2 ( 2 ÷ 2 - 2 ) } ÷ 2 ] ÷ 2
2 [ { 2 - 2 ( 1 - 2 ) } ÷ 2 ] ÷ 2
2 [ { 2 - 2 ( - 1 ) } ÷ 2 ] ÷ 2
2 [ { 2 + 2 } ÷ 2 ] ÷ 2
2 [ 4 ÷ 2 ] ÷ 2
2 ( 2 ) ÷ 2
4 ÷ 2

Step-by-step explanation:
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:
-3+6y = 9x
6y = 9x+3
y = 9/6x+3/6
y = 3/2x+1/2 ⇒ slope-intercept form
