Answer:
14
Step-by-step explanation:
add both values and equals them to 180.then solve the equation and find X you will get 14
Answer: I think x = 14
7x - 1 + 6x - 1 + 7x -1 + 6x -1
(vertically opposite angles are equal)
collect like terms:
26x - 4 = 360
(angles around a point = 360 degrees)
+4 to both sides
26x = 364
x = 14
