bc = ad = 75 Tan adb = 160/75 = 2.1333 (4dp), so angle adb = 64.885°.
It is formed by the diagonal of a rectangle
a right angle is formed because the angle measures 90 degrees
straight angle
central angle central angle
Since a field is rectangular, it has 4 right angles, each of them measuring 90°

An angle cannot be formed by only one ray. However, an angle formed by two opposite rays is called a straight angle.
A 90 degree angle is formed at a right angle.
If you mean an angle then an angle is formed by two straight lines meeting at a vertex.
The angle formed by a horizontal line is 180o.
To calculate the beam spread angle in a rectangular beam transducer probe, you can use trigonometry. The beam spread angle can be calculated using the dimensions of the probe, usually the width and height of the rectangular aperture. You can use trigonometric functions like tangent or arcsine to determine the angle of beam spread based on the dimensions of the probe.
A cuboid has rectangular faces.
A rectangular shape cannot have a diameter, which is a characteristic of a circle.
