The slope is 8-1/2 divided by 9 = 0.9444...(rounded, repeating)The angle of the slope is whatever angle has a tangent of (8-1/2)/9 .That angle is 43.36 degrees. (rounded)That makes sense, because we know that if the tread and riser were equal,then the angle would be 45 degrees.

The slope is the rise/run.And then angle of incline = arctan(slope).

Most loose, not compacted, sands and silts have an angle of repose, measured from the horizontal, of 35 degrees.

Hold a ruler level, then slope the ruler to an angle of 45 degrees. The inclination of the ruler is now 45 degrees. So if rock has been altered as to be unlevel, then the angle from the level is the rock beds inclination.

There are many ways to find the angle of a slope. One easy practical way to see if a slope is 10 degrees is to have a 1 metre long (1000 mm) straight edge and put one end on the slope surface while holding it horizontal with a spirit level. The "free" end will be 176 mm (176.327 mm) off the surface if the slope is 10 degrees. (Tan 100 = 176 / 1000 to nearest round figures).

The angle of depression is equal to the angle of elevation, so use the sine ratio to find the angle. sine = opposite (the vertical drop) divided by the hypotenuse (the ski slope) sine = 100/250 = 2/5 or 0.4 sine-1(0.4) = 23.57817848 degrees which is about 24 degrees

Step 1: Divide the percentage slope by 100. Step 2: Calculate arctan or tan-1 [=atan() in Excel] of that value to give the angle. Advanced mathematicians use radians to measure angles, and Excel calculates the angle in radians. However, if you need it in degrees, multiply the last answer by 180/pi. On most calculators you will need to ensure that angles are measured in degrees. Thus, if you have a 15% slope, step 1 gives 0.15 and step 2 gives an angle of 0.1489 radians, which is equal to 8.53 degrees (approx).

The angle at which loose material will not slide down a slope is called the angle of repose. It is the maximum angle at which an inclined surface formed of a particular loose material can remain stable without sliding. The angle of repose varies depending on the size, shape, and friction of the particles making up the material.
