Right Triangle Acute Angle from Opposite and Adjacent Legs Calculator
Right Triangle Acute Angle from Opposite and Adjacent Legs. Example: Opposite: 3 m, Adjacent: 4 m gives 36.8698976458 degrees. Right triangle only; positive perpendicular legs in meters; returns angle adjacent to supplied adjacent leg. Only this original stated job is proposed, not full historical source coverage. Input domains and output unit must be visible.
Right triangle only; positive perpendicular legs in meters; returns angle adjacent to supplied adjacent leg. Only this original stated job is proposed, not full historical source coverage. Input domains and output unit must be visible. Derivation: Tangent ratio of the named acute angle is opposite/adjacent.
Accepted inputs: Opposite: 0.001 to 10,000 m; Adjacent: 0.001 to 10,000 m.
Right Triangle Acute Angle from Opposite and Adjacent Legs
How the calculation works
θ=atan(opposite/adjacent)×180/π
Worked example
With opposite 3 m, adjacent 4 m, right triangle acute angle from opposite and adjacent legs is 36.86989765 degrees.
Assumptions and limits
Right triangle only; positive perpendicular legs in meters; returns angle adjacent to supplied adjacent leg. Only this original stated job is proposed, not full historical source coverage. Input domains and output unit must be visible. Derivation: Tangent ratio of the named acute angle is opposite/adjacent.
