B) Cannot be determined for concave polygons
You can only find the measure of the interior angles of a regular polygon, not a concave polygon. The sides and angles must be equal to each other in order to be able to find the measure of each interior angle.
Answer:
9/4
Step-by-step explanation:
5×|-2-7(3)|-2×17
5×|-2-21|-34
5×|-23|-34
5×23-34
115-34=81
22+sq rt(7×28) 28=4×7 sq rt= 2×2×7×7
22+2×7=22+14=36
81÷9/36÷9=9/4
