<h3>9 × 6</h3>
Because the surface area is rectangle and the area of rectangle is length × width
length = 9
width = 6.
so 9×6
The angle relationship that best describes angles BAC and DAC is adjacent angles
<h3>What are adjacent angles?</h3>
Adjacent angles are two angles that have a common side and a common vertex but do not overlap in any way.
The common vertex of the angle BAE and FAC is A.
The angles share the same vertex and the same side.
Therefore, the angle relationship that best describes angles BAC and DAC is adjacent angles
