What is the value of x in the diagram below?-88-100-95-151 Please help, will give branliest.

Answer:The answer to your question is: x = 100Step-by-step explanation:It's a polygon of 7 sidesThe sum of internal angles in a polygon equals 180(n-2), where n = # of sides                               Internal angles = 180(7-2)                                       = 180(5)                                      = 900°       (x + 50) + (x + 50) + (x + 50) + x + x + x + (x + 50) = 900       4(x + 50) + 3x = 900       4x + 200 + 3x = 900       7x = 900 - 200       7x = 700       x = 700 / 7       x = 100
