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°
This is your answer, hope this helps :D !
Answer: See below
Explanation:
1a.
-4 • 1 = 8(y-5)
-4 = 8y - 40
-8y = -40 + 4
-8y = -36
Y = -36/-8
Y = 9/2
1b.
3c - 6 = -6 + 9(c+9)
3c - 6 = -6 + 9c + 81
3c - 9c = 75 + 6
-6c = 81
C = 81/-6
C = 27/-2
2a.
6(p-2) = -2 + 3
6p - 12 = 1
6p = 13
P = 13/6
2b.
3x - 4 = -3 + 4(x - 3)
3x - 4 = -3 + 4x - 12
3x - 4x = -15 + 4
-x = -11
X = 11
I think it is 20 because you have to multiply and then divide them add 11 then subtract 9 idk what I am saying
