MAIN SPAN FASCIA MITER ANGLE arctan (sin Main Common Pitch Angle ÷ tan Adjacent Deck Angle) ADJACENT SPAN FASCIA MITER ANGLE arctan (sin Adjacent Common Pitch Angle ÷ tan Main Deck Angle) MAIN SPAN ANGLE between EAVE and HIP RIDGE arctan (tan Main Deck Angle ÷ cos Main Common Pitch Angle) ADJACENT SPAN ANGLE between EAVE and HIP RIDGE arctan (tan Adjacent Deck Angle ÷ cos Adjacent Common Pitch Angle) Usage of the Fascia Miter Angle and Angle between Eave and Hip Ridge is consistent for the Main Span and Adjacent Span in the following two formulas, hence the span is not specified. FASCIA BEVEL ANGLE arctan (cos Fascia Miter Angle ÷ tan Angle between Eave and Hip Ridge) ANGLE between MATCHING FACES of FASCIA arccos (sin Fascia Miter Angle cos Angle between Eave and Hip Ridge) |
