1. Arithmetic sequence of pentagon angles ●○○○○ 10 ptsLet $v$, $w$, $x$, $y$, and $z$ be the degree measures of the five angles of a pentagon. Suppose $v<w<x<y<z$ and $v$, $w$, $x$, $y$, $z$ form an arithmetic sequence. Find the value of $x$ in degrees.
2. Interior angle of a regular pentagon ●○○○○ 10 ptsFind the measure, in degrees, of an interior angle of a regular pentagon.
3. Missing angles of a heptagon ●○○○○ 10 ptsFive angles of a heptagon have measures $80^\circ$, $85^\circ$, $175^\circ$, $90^\circ$ and $140^\circ$. The other two angles are congruent. Find the measure of each of the other two angles, in degrees.
