Triangle ABC has side lengths c = 29, a = 40, and b = 40. Find the inradius of triangle ABC. Find the circumradius of triangle ABC.
Acute isosceles triangle.
Sides: a = 40 b = 40 c = 29 Area: T = 540.551 Perimeter: p = 109 Semi-perimeter: s = 54.5
T=rs r=T / s = 540.55 / 54.5 =9.92 - the Inradius.
R=[abc] / [4rs] ==[40 * 40 * 29] / [4 * 9.918 * 54.5] R==21.46 - the Circumradius.
