Find the measure of each interior angle
diamong [38]
\bf \textit{sum of all interior angles of a polygon}\\\\&#10;180(n-2)\quad &#10;\begin{cases}&#10;n=\textit{number of sides}\\&#10;---------\\&#10;n=10&#10;\end{cases}\implies 180(10-2)\implies 1440\\\\&#10;-------------------------------\\\\&#10;\begin{array}{lclll}&#10;&x + 5\\&x + 10\\&x + 20\\&x + 30\\&x + 35\\&x + 40\\&x + 60\\&x + 70\\&x + 80\\+&x + 90\\&#10;&----\\&#10;&10x+440&#10;\end{array}\implies &#10;\begin{array}{llll}&#10;10x+440=1440&#10;\\\\\\&#10;10x=1000&#10;\\\\\\&#10;x=\cfrac{1000}{10}\implies x=100&#10;\end{array}

so.. to get every angle, simply plug in 10 for "x" for each.
