The definition of a right angle is an angle measuring 90 degrees. You don't have to calculate anything.
Here are 2 examples:He was glancing nervously at his teacher.Why were you glancing nervously at me?
A glancing collision is a type of impact between two objects where they come into contact at an angle rather than head-on. This can result in the objects deflecting or sliding off each other rather than directly impacting. Glancing collisions can affect the direction and outcomes of the objects' motion after the collision.

No. At least not in the sense of "glancing" (looking). Glance is the noun, and glancing is a gerund noun. The word glancing can be an adjective when used to mean an indirect impact, i.e. a glancing blow.
Balance with controlling angle
The angle of reflection will also be 30 degrees. The angle of incidence is equal to the angle of reflection when light reflects off a smooth surface like a mirror.
Yes, the angle at which two objects collide can affect the force of impact. In a collision, the force of impact is dependent on both the angle and the velocity of the objects involved. A head-on collision, for example, will generally result in a higher force of impact compared to a glancing blow at an angle.
Yes.
The deviation of the incident ray and the reflected ray at a reflecting surface is called "reflection angle". This angle is measured relative to the normal (a line perpendicular to the surface) at the point of incidence. The reflection angle is equal to the incident angle for perfectly smooth and flat surfaces.
the tangent of an angle is equal to the length of the opposite side from the angle divided by the length of the side adjacent to the angle.
There is not enough information to calculate an angle. At the very least, you need to know that the polygon is regular. You do not know that.
