Obtuse scalene triangle.

Sides: a = 7   b = 9   c = 3.31

Area: T = 10.324

Perimeter: p = 19.31

Semiperimeter:
s = 9.655

Angle ∠ A = α = 43.868° = 43°52'6″ = 0.766 rad

Angle
∠ B = β = 117° = 2.042 rad

Angle
∠ C = γ = 19.132° = 19°7'54″ = 0.334 rad

Height: ha = 2.95

Height:
hb = 2.294

Height:
hc = 6.237

Median: ma = 5.808

Median:
mb = 3.119

Median:
mc = 7.891


Inradius: r = 1.069

Circumradius:
R = 5.05

Vertex coordinates: A[3.31; 0] B[0; 0] C[-3.178; 6.237]

Centroid:
CG[0.044; 2.079]

Coordinates of the circumcenter:
U[1.655; 4.772]
