Question
question what is the sum of the interior angles of the polygon pictured below?
Step1: 确定多边形边数
观察图形可知,该多边形有\(23\)条边,即\(n = 23\)。
Step2: 运用多边形内角和公式
多边形内角和公式为\((n - 2)\times180^{\circ}\),将\(n = 23\)代入公式,得到\((23 - 2)\times180^{\circ}\)。
Step3: 计算内角和
先计算括号内的值:\(23 - 2 = 21\),再计算乘法:\(21\times180^{\circ}=3780^{\circ}\)。
