Wie finden Sie die Fläche eines triangleABC, wenn angleC = 62 ^ @ , b = 23.9 und a = 31.6 ?
Antworten:
color(brown)("Area of triangle ") color(green)(A_t = 333.42) color(purple)(" sq units"
Erläuterung:
"Given : a = 31.6, b = 23.9, hat C = 62^@
Anwenden der Formel A_t = (1/2) a b sin C, color(brown)(" using 2 sides and the included angle"
A_t = (1/2) * 31.6 * 23.9 * sin 62 = 333.42 " sq units"
