Question

the front view of a recycle bin is shaped like a trapezoid. what is the measure of the remaining angle? 72° 108° 108° o 72° o 144° o 198° o 252°

Explanation:

Step1: Recall sum of angles in a trapezoid

The sum of interior angles of a quadrilateral (a trapezoid is a quadrilateral) is 360°.

Step2: Add the given angles

The given angles are 72°, 108° and 108°. Their sum is 72° + 108°+ 108° = 288°.

Step3: Find the remaining angle

Let the remaining angle be \(x\). Then \(x=360° - 288°=72°\).

Answer:

72°
