What is the measure of each interior angle of a regular octagon?​

100 points, hi, i’m not sure how to get the equation from the graph and table.

Given: jk ||lm prove: _2 = 27 statement justification 1. jk ||lm 1. given 2.26 = 27 3.22 = 26 2. 3. 4. _2 = 27 4. corresponding angles theorem transitive property of equality vertical angles theorem substitution property of equality

Simplify each expression. use positive exponents. show work . (x –2 y –4 x 3 ) –2
