what is the sum of the internal angles?
sum of internal angles=
blank 1:

Explanation:

Step1: Identify the formula for sum of internal angles

The formula for the sum of internal angles of a polygon is \((n - 2)\times180^{\circ}\), where \(n\) is the number of sides.

Step2: Determine the number of sides of the polygon

The given polygon is an octagon. An octagon has \(n = 8\) sides.

Step3: Calculate the sum of internal angles

Substitute \(n = 8\) into the formula: \((8 - 2)\times180^{\circ}=6\times180^{\circ} = 1080^{\circ}\)

Answer:

\(1080\)
