A decagon has interior angle measures of 156, 178, 124, 132, 138, 142, 116, 178, and 159. Find the measure of the missing angle. (Show work) please and thanks!
I beilive I have heard that a decagon equals 1440 degree's what you can do lets see you have 9 angles degree mesaurments on here add them then subtract the sum from 1440 after that your diffrence will be your answer.....
like this
\(156 + 178 + 124 +132 +138+142+116+178 +159 = sum\)
\( 1440 - sum = difference \)
\(Difference = answer.\)
