I'm not sure that I understand the question but if you are asking how to find the normal component to a force that is acting on an angle then you should break up the force vector into two components that act at right angles to each other and where one is 'normal' to the (surface of) the object. Normal in this case means "at right angles to a tangent" (I assume that the most common case in dynamics is for the extension of that 'normal' vector to go through the center of gravity of the object).

How do you find the angle in the work done?
You measure it. Depending on the information provided, you can also calculate it, for example using trigonometry. ======================== Work done= Force vector . Displacement vector=Force*displacement*cos a, where a is the angle between the force and the displacement. So you have the values of work force and displacement then you can do the cosine inverse of the ratio of work done to the product of the force and displacement. That will give you the angle.
Can you give me an experiment to calculate the coefficient of static and dynamic friction?
Get a block of known mass, a protractor and a board; the materials should be chosen as those for which you want to find the friction coefficients. Place the block on the board and gradually increase the angle of the board while keeping track of the angle the board makes with horizontal. The angle at which the block slips is crucial. The friction force opposes the movement of the block based on the normal force applied on the block by the board. As you increase the angle, the normal force decreases. F = uN where F is the friction force, N is the normal force and u is the coefficient of friction, in this case, static. Using the angle at which the block slips, calculate N; N = m sin(@) where m is the mass of the block, and @ is the measured angle. Now F must be equal to the force of gravity pulling on the block parallel to the board, otherwise the block would slip (and it does precisely at the measured angle) so; F = m cos(@) where m is the mass of the block and @ is the measured angle. Now that F and N are known, use the aforementioned relationship to calculate u. This value should be non-negative and has no units. As for dynamic friction; let the block slide from the top of the board when it is at a high angle and gradually decrease the angle until the block comes to a stop on the board due to friction. This should be done in trials of larger degrees until a working angle is found, then more precise trials can commence. When such an angle is found that any higher angle allows the block to keep going all the way to the bottom, the same calculations as above must be repeated to find the coefficient of dynamic friction.
How does the steepness of a ramp affect how fast an object moves?
The steepness of the ramp affects the direction of the normal force of the object on a ramp (which is always perpendicular to the ramp). The net gravitational force is always straight down.Using the angle of inclination of the ramp with Trigonometry, you can find the vector forces of gravity perpendicular and parallel to the normal force which makes up the net gravitational force. The parallel portion is in the same direction of the ball rolling down the ramp. This will give you your force of acceleration, which you can use in basic equations to find the velocity of the object.The steeper the ramp, the faster the object rolls down. A ramp of 0 degrees would result in a ball just sitting on the ramp as normal force and gravitational forces cancel each other. A ramp of 90 degrees would be like a cliff and this would produce the fastest velocity since the ball is moving in the same direction as the force of gravity in free fall. A ramp with an angle between these means that part of the gravitational force is being offset by the normal force.

How do you find the force of an object with just the mass and angle of object?
You cannot find the force without knowing the velocity or acceleration of the object.

How can you find the coefficient of friction force only given mass and theta?
The coefficient of friction is the tangent of the angle theta where the angle is measured from horizontal when the mass first starts to slip
How do you find the angle of reflection off of a mirror?
The angle of reflection (θr) off a planar surface (eg. mirror) is equal to the angle of incidence (θi) on that surface. They are measured with respect to the normal, which is an imaginary line drawn perpendicular to the surface. Or, in simpler terms, the angle of reflection is the same as the angle of incidence.

How do you find the normal force of a 25 kg object being pulled by a rope at a tension of 120 N along a frictionless surface at an angle of 30 degrees?
I could be totally wrong but I believe you must take into account the forces on the object in the vertical direction. In this case, the object is being pulled by a rope with a tension of 120 N. The vertical force would therefore be 120 sin(30) Normally W = [F normal] with no vertical force. However, since there is a vertical force: W = [F normal] + [120 sin (30)] (25 kg X 9.8 m/s2) = [F normal] + [120 sin (30)] 245 N - 60 N = [F normal] 185 N = [F normal] I apologize if this is incorrect as I haven't been in a physics class in over 4 years. Good luck!
