Question

the sum of the angles of a rectangle is.

Explanation:

Step1: Recall the formula for the sum of interior angles of a polygon

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

Step2: Determine the number of sides of a rectangle

A rectangle has \(n = 4\) sides.

Step3: Calculate the sum of interior angles

Substitute \(n = 4\) into the formula: \((4 - 2)\times180^{\circ}=2\times180^{\circ} = 360^{\circ}\)

Answer:

\(360^{\circ}\)
