Answer:

Look below

Step-by-step explanation:

A. This is a 5-sided figure (pentagon) therefore the interior angles would add up to 540 degrees. We can use this to set up an equation:

x+100+112+113+117=540

Add like terms

x+442=540

Subtract 442 from both sides

x=98

B. This is a 6-sided figure (hexagon) therefore the interior angles would add up to 720 degrees. We can use this to set up an equation:

x+90+90+130+140+150=720

Add like terms

x+600=720

Subtract 600 from both sides

x=120
