05 Algebra Find the missing angle measures in each figure. 26. (x + 11) 24. 25. 95° 124° 749 (x - 13) bo 110° 104° polygon that is not

Answer 1

The sum of the internal angles of that figure is equal to 720, therefore:

`\begin{gathered} 90+n+n+n+n+90=720 \\ add_{\text{ }}like_{\text{ }}terms\colon \\ 180+4n=720 \\ solve_{\text{ }}for_{\text{ }}n\colon \\ 4n=720-180 \\ 4n=540 \\ n=(540)/(4) \\ n=135 \end{gathered}`
