The correct answer is (5,-7) Hope that helps!
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°
64
5/8= 40. 3/8= 24
1:4 of 40
1= 8. 1*8=8
Answer= 8
