Question

to find area of triangle h=10 & b=8

Answer 1

Area Of Triangle∆

= 1/2 × B × H

= 1/2 × 8 × 10

= 1/2 × 80

= 40 (Unit)

Answer 2

here is your answer


Right scalene Pythagorean triangle.

Sides: a = 6   b = 8   c = 10

Area: T = 24
Perimeter: p = 24
Semiperimeter: s = 12

Angle ∠ A = α = 36.87° = 36°52'12″ = 0.644 rad
Angle ∠ B = β = 53.13° = 53°7'48″ = 0.927 rad
Angle ∠ C = γ = 90° = 1.571 rad

Height: ha = 8
Height: hb = 6
Height: hc = 4.8

Median: ma = 8.544
Median: mb = 7.211
Median: mc = 5

Inradius: r = 2
Circumradius: R = 5

Vertex coordinates: A[10; 0] B[0; 0] C[3.6; 4.8]
Centroid: CG[4.533; 1.6]
Coordinates of the circumscribed circle: U[5; 0]
Coordinates of the inscribed circle: I[4; 2]

Exterior(or external, outer) angles of the triangle: 
∠ A' = α' = 143.13° = 143°7'48″ = 0.644 rad
∠ B' = β' = 126.87° = 126°52'12″ = 0.927 rad
∠ C' = γ' = 90° = 1.571 rad

Calculate another triangle 




How did we calculate this triangle?

Now we know the lengths of all three sides of the triangle and the triangle is uniquely determined. Next we calculate another its characteristics - same procedure ascalculation of the triangle from the known three sides SSS.



1. The triangle circumference is the sum of the lengths of its three sides



2. Semiperimeter of the triangle



3. The triangle area using Heron's formula



4. Calculate the heights of the triangle from its area.



5. Calculation of the inner angles of the triangle using a Law of Cosines
