the measure of angles of a hexagon are x degree , (x-5) degrees , (x-5) degrees , (2x-5) degrees , (2x-5) degrees , (2x+20) find the value of x

x = 80°

Step-by-step explanation:

The sum of the interior angles of a hexagon is 720 degrees. So,

x + (x - 5) + (x - 5) + (2x - 5) + (2x - 5) + (2x + 20) = 720

Eliminating parenthesis

x + x - 5 + x - 5 + 2x - 5 + 2x - 5 + 2x + 20 = 720

Adding and subtracting

9x + 0 = 720

Isolating x

x = 720/9

x = 80

i think it is c, not positive though
