Answer:

x=58

Step-by-step explanation:

ok this is a 5 sided polygon

5 sided polygon has 540 degrees

540-90-120-108-100= the unkown angle

122

but look at the line exterior plus interior = 180 degrees

180=122+x

subtract 122 from both sides

13 x-2(8+5 x)=12-11 x
77julia77 [94]

Expand

13x - 16 - 10x = 12 - 11x

Simplify 13x - 16 - 10x to 3x - 16

3x - 16 = 12 - 11x

Add 16 to both sides

3x = 12 - 11x + 16

Simplify 12 - 11x + 16 to -11x + 28

3x = -11x + 28

Add 11x to both sides

3x + 11x = 28

Simplify 3x + 11x to 14x

14x = 28

Divide both sides by 14

x = 28/14

Simplify 28/14 to 2

x = 2
