Answer:
d = 10
Step-by-step explanation:
50 + 2 ( 2 - d ) = 3 ( 1 + d ) + 1
50 + 4 - 2d = 3 + 3d + 1
54 - 2d = 4 + 3d
- 4 -4
50 - 2d = 3d
+2d +2d
50 = 5d
50/5
d = 10
Answer:
x = 130
Step-by-step explanation:
The sum of the exterior angles of a polygon is always 360
140 + x + 56+ 34 = 360
Combine like terms
230 +x = 360
Subtract 230 from each side
230+x-230 = 360-230
x =130
