The angle, or pitch, of a roof is calculated by the number of inches it rises vertically for every 12 inches it extends horizontally.
It is not clear what numbers are represented by the alphabetic characters that appear in the sequence in the question.
Sin(10)*12 = 12*sin(10) = 12*0.1736 = 2.0838, approx.
1. Add all the numbers together to get the total. (e.g. 3+4+5= 12)2. Divide each number by the total, noting your results (3/12= 0.25, 4/12+0.3333, 5/12=0.1467)3. Multiply each of the results by 360, that will give you your answer in degrees (0.25x360= 90 degrees, 0.3333x360= 120 degrees, 0.1437x360= 150 degrees4. Add the answers together to insure you haven't made any mistakes. If you have made a mistake you will not get 360. (90+120+150= 360)An easier way to calculate the angles for a pie chart is to:divide 360 by the total of your informationkeep note of the division answer then multiply every number by your division answeradd the angles together to make sure you have 360
A 12/12 is 45 degrees. If you set a 45 degree piece of wood on the roof it should be level.
