20% = 72 degrees

I'm not sure exactly what this question is asking, but I will attempt to answer. An angle on the unit circle is created by drawing a straight line from the origin to a point on the circle. The x-coordinate of a point corresponds to the cosine of the angle. For example: cos(90o) = 0 The y-coordinate of a point corresponds to the sine of the angle. For example: sin(270o) = -1
sin(20) = 0.3420 (approx).
I believe about 20 degrees.
To solve for the cosine (COS) of an angle, you can use the unit circle, where the cosine of an angle corresponds to the x-coordinate of the point on the circle at that angle. Alternatively, you can use trigonometric identities or the cosine function on a scientific calculator by inputting the angle in degrees or radians. For specific problem solving, using the cosine rule in triangles may also be applicable to find unknown sides or angles.

To convert a percentage to an angle in degrees, you multiply the percentage by 360 degrees. Therefore, 11 percent as an angle is calculated as (11/100 \times 360 = 39.6) degrees. Thus, 11 percent corresponds to an angle of 39.6 degrees.
20% of a 360o circle is 72o

The atomic mass of hydrogen is 1 and that of carbon is 12, to the nearest integer. Therefore, a compound that contains 20 percent hydrogen and 80 percent carbon contains atoms of carbon in the ratio of 20:(80/12) = 20:(20/3) = 20 X 3/20 = 3. The smallest whole number ratio corresponding to this is 1:3, which corresponds to an empirical formula of CH3. (However, since carbon normally has a valence of 4 in hydrocarbons, the actual formula is probably C2H6.)

The key is to recognize that "the angle of INCIDENCE is equal to the angle of REFLECTION", for an 'Elastic' collision. So the answer is 20 degrees.
