The answer is B. Have a nice day
Answer:
Step-by-step explanation:
Sum of all the angles of 12 sided polygon= (n -2)*180
= (12 - 2 )*180 = 10 * 180 = 1800
Four interior angle each of xº + 8 interior angles each of 2xº = 1800
4*x + 8*2x = 1800
4x + 16x = 1800
20x = 1800
x = 1800/20
x = 90°
3y - y + 8 - 2 = 20
3y - y = 2y
8 - 2 = 6
2y + 6 = 20
2y = 20 - 6
y = 10 - 3
the answer is: y = 7
Answer:
112 degrees
Step-by-step explanation:
since the lines are perpendicular and have a single intersecting line on both lines, <7 will also be 112.
Hope this helped~!
Pretty sure the answer is B.
