QuestionНайди площадь треугольника MNK, если MN=25\mathrm{MN}=25 дм, MK=330\mathrm{MK}=330 см, а угол M равен 3030^{\circ}
Запиши ответ числом. S=qм2\mathrm{S}=\square \mathrm{qм}^{2}

Studdy Solution
Вычисляем площадь:
S=12×2.5×3.3×0.5 S = \frac{1}{2} \times 2.5 \times 3.3 \times 0.5 =0.5×2.5×3.3×0.5 = 0.5 \times 2.5 \times 3.3 \times 0.5 =0.5×1.25×3.3 = 0.5 \times 1.25 \times 3.3 =0.625×3.3 = 0.625 \times 3.3 =2.0625 = 2.0625
Площадь треугольника:
2.0625м2 \boxed{2.0625} \, \text{м}^2
