Answer 1

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
