Answer:
The angle is 68.2 degrees
Step-by-step explanation:
Let us have the shorter side as the width
In that case, the opposite will be the length which is 8 cm
The diagonal is the hypotenuse
The short side is the adjacent
The trigonometric ratio that links the opposite and the adjacent is the tan
tan of an angle is the ratio of its opposite to the adjacent
In this case,
tan theta = 8/3.2
theta = arc tan (8/3.2)
theta = 68.2 degrees
