2. Find the perimeter of the triangle A(l, 4) B (- 5, - 3) C (5, - 4)

Dont look at me like that

Step-by-step explanation:

*schwing*

Acute scalene triangle. All calculations (i love math)

Sides: a = 10.05   b = 8.944   c = 9.22

Area: T = 38

Perimeter: p = 28.214

Semiperimeter: s = 14.107

Angle ∠ A = α = 67.166° = 67°9'59″ = 1.172 rad

Angle ∠ B = β = 55.109° = 55°6'33″ = 0.962 rad

Angle ∠ C = γ = 57.724° = 57°43'28″ = 1.007 rad

Height: ha = 7.562

Height: hb = 8.497

Height: hc = 8.243

Median: ma = 7.566

Median: mb = 8.544

Median: mc = 8.322

Inradius: r = 2.694

Circumradius: R = 5.452

Vertex coordinates: A[1; 4] B[-5; -3] C[5; -4]

Centroid: CG[0.333; -1]

Coordinates of the circumscribed circle: U[0; 0]

Coordinates of the inscribed circle: I[1.879; 2.694]

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

∠ A' = α' = 112.834° = 112°50'1″ = 1.172 rad

∠ B' = β' = 124.891° = 124°53'27″ = 0.962 rad

∠ C' = γ' = 122.276° = 122°16'32″ = 1.007 rad
