8x - 19 = 36
8x = 55
x = 55/8 = 6 7/8
-2x + 19 = -66
-2x = -85
2x = 85
x = 42 1/2

13/2170 = 0.006 (to 3 decimal places)
228.5 I believe. 14/49 is 3.5. 18+7 is 25x9 is 225. 225+3.5 would be 228.5
Answer:
x = 27
Step-by-step explanation:
AC // DE
m∠ABD ≅ m∠BDE = 72°
m∠ADB + m∠BDE + m∠EDF = 180°
2x + 72° + 2x = 180°
4x = 108°
x = 27°
