Solution (1):

Note that:

Sum of interior angles = 180°

This means that...

5x + 3x + 2 + 130 = 180

Finding the value of x.

5x + 3x + 2 + 130 = 180
=> 8x + 132 = 180
=> 8x = 180 - 132
=> 8x = 48
=> x = 6

Solution (2):

Note that:

Sum of interior angles = 180°

This means that...

x + 66 + x + 86 + 50 = 180°

Finding the value of x.

x + 66 + x + 86 + 50 = 180°
=> 2x + 202 = 180°
=> 2x = -22
=> x = -11
