Answer:
x=68
Step-by-step explanation:
Five sides means the shape is equal to 540 degrees. So set up an equation that is equal to 540 degrees.
540=(2x-2)+(x-10)+(x+8)+(3x)+(x)
Take off the parentheses because there's nothing to simplify with them.
540=2x-2+x-10+x+8+3x+x
Then you simplify and get.
540 =8x-4
Then get x alone.
8x=544
Divide each side by 8 to get x alone
x=68
