Решение:
Угол:
γ° = 180 - α° - β°
= 180 - 45° - 60°
= 75°
Сторона:
a = c·
= 500·
= 500·
= 500·0.7321
= 366.05
Сторона:
b = c·
= 500·
= 500·
= 500·0.8966
= 448.3
Периметр:
P = a + b + c
= 366.05 + 448.3 + 500
= 1314.4
Площадь:
p =
S =√p·(p-a)·(p-b)·(p-c)
=√657.18·(657.18-366.05)·(657.18-448.3)·(657.18-500)
=√657.18 · 291.13 · 208.88 · 157.18
=√6281530049.4739
= 79256.1
