Miter and bevel are assumed to be cut from the side or plumb face of the Hip rafter. Usage of the Common Pitch Angle and Deck Angle is consistent for the Main Span and Adjacent Span. Therefore the span in not specified as in the case of the fascia angle formulas. HIP RAFTER MITER ANGLE arctan (cos Common Pitch Angle sin Common Pitch Angle cos Deck Angle ÷ tan Deck Angle) HIP RAFTER BEVEL ANGLE arcsin (cos Common Pitch Angle cos Deck Angle) |
