Spike's Calculators

Calculate the horizontal length (HL) from a slope in degrees and the slope length (SL).
Calculator uses the cosine function "*The cosine of an angle in a right angled triangle is the ratio that multiplies the slope length and results in the horizontal length.*"

Formula: HL = cosine(degrees * π ÷ 180) * SL

length of slope line = 14' 11" converted to inches --- 12 * 14 + 11 = 179"
