The Answer is Height: hb = 12.923
Acute scalene triangle.Sides: a = 15 b = 13 c = 14
Area: T = 84
Perimeter: p = 42
Semiperimeter: s = 21
Angle ∠ A = α = 67.38° = 67°22'49″ = 1.176 rad
Angle ∠ B = β = 53.13° = 53°7'48″ = 0.927 rad
Angle ∠ C = γ = 59.49° = 59°29'23″ = 1.038 rad
Height: ha = 11.2
Height: hb = 12.923 <- Answer
Height: hc = 12
Median: ma = 11.236
Median: mb = 12.971
Median: mc = 12.166
