    2.) The area of a regular octagon is 35 cm². What is the area of a regular octagon with sides three times as long? My answer: 315 cm². Is that correct?

    \[\frac{ 360 }{ n }~\rightarrow~n=number~of~sides \rightarrow \frac{ 360 }{ 10 }=36 º\]

    they also want to know about angle 2. you have an isosceles triangle so you can figure it out.

    Oh right. So for the measure of the 2nd angle, you need to use this.\[\huge m∠2=\frac{ 180-m∠1 }{ 2 }\]
