Answer:

this is the anwser

Step-by-step explanation:

4 12 13 triangle

Obtuse scalene triangle.

Sides: a = 4   b = 12   c = 13

Area: T = 23.894

Perimeter: p = 29

Semiperimeter: s = 14.5

Angle ∠ A = α = 17.839° = 17°50'19″ = 0.311 rad

Angle ∠ B = β = 66.782° = 66°46'55″ = 1.166 rad

Angle ∠ C = γ = 95.379° = 95°22'46″ = 1.665 rad

Height: ha = 11.947

Height: hb = 3.982

Height: hc = 3.676

Median: ma = 12.349

Median: mb = 7.517

Median: mc = 6.144

Inradius: r = 1.648

Circumradius: R = 6.529

Vertex coordinates: A[13; 0] B[0; 0] C[1.577; 3.676]

Centroid: CG[4.859; 1.225]

Coordinates of the circumscribed circle: U[6.5; -0.612]

Coordinates of the inscribed circle: I[2.5; 1.648]

Exterior (or external, outer) angles of the triangle:

∠ A' = α' = 162.161° = 162°9'41″ = 0.311 rad

∠ B' = β' = 113.218° = 113°13'5″ = 1.166 rad
