Don't look directly at it, just a quick look
Deviation due to reflection. This equals to twice the glancing angle.
The definition of a right angle is an angle measuring 90 degrees. You don't have to calculate anything.
You have given the glancing angle as 30 degree. So the angle of incidence = 90-30 = 60 deg As i = r by the law of reflection the angle of reflection = 60 deg
Here are 2 examples:He was glancing nervously at his teacher.Why were you glancing nervously at me?
Angle A=opposite/adjacent shift tan Angle B=90-Angle A
Balance with controlling angle
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.
Yes.
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.
Calculate the percentage that a particular sector represents of the total value. Then the angle size is 3.6 times the percentage.
There is no term to calculate any angle of any irregular polygon. For a regular polygon with n sides, each exterior angle is 360/n degrees. Each interior angle is (180 - exterior angle).
