Решение:
Угол:
α° = 180 - γ° - β°
= 180 - 56° - 36°
= 88°
Высота :
hc = a·sin(β°)
= 53.8·sin(36°)
= 53.8·0.5878
= 31.62
Сторона:
b = a·
= 53.8·
= 53.8·
= 53.8·0.5882
= 31.65
Сторона:
c = a·
= 53.8·
= 53.8·
= 53.8·0.8295
= 44.63
Периметр:
P = a + b + c
= 53.8 + 31.65 + 44.63
= 130.08
Площадь:
p =
S =√p·(p-a)·(p-b)·(p-c)
=√65.04·(65.04-53.8)·(65.04-31.65)·(65.04-44.63)
=√65.04 · 11.24 · 33.39 · 20.41
=√498202.91879904
= 705.83
