Answer:
The area is 25 :)
Explanation:
This Is An Obtuse scalene triangle.
Sides: a = 17.205 b = 13.454 c = 5
Area: T = 25
Perimeter: p = 35.658
Angle ∠ A = α = 131.987° = 131°59'14″ = 2.304 rad
Angle ∠ B = β = 35.538° = 35°32'16″ = 0.62 rad
Angle ∠ C = γ = 12.475° = 12°28'30″ = 0.218 rad
Height: ha = 2.906
Height: hb = 3.716
Height: hc = 10
Median: ma = 5.385
Median: mb = 10.735
Median: mc = 15.24
Inradius: r = 1.402
Circumradius: R = 11.573
Vertex coordinates: A[3; 4] B[8; 4] C[-6; -6]
Centroid: CG[1.667; 0.667]
Coordinates of the circumscribed circle: U[0; 0]
Coordinates of the inscribed circle: I[1.963; 1.402]
Exterior (or external, outer) angles of the triangle:
∠ A' = α' = 48.013° = 48°46″ = 2.304 rad
∠ B' = β' = 144.462° = 144°27'44″ = 0.62 rad
∠ C' = γ' = 167.525° = 167°31'30″ = 0.218 rad
