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"#
