Решение:
Угол:
β° = 180 - γ° - α°
= 180 - 90° - 3.30°
= 86.7°
Сторона:
a = b·
= 160·
= 160·
= 160·0.05766
= 9.226
Сторона:
c = b·
= 160·
= 160·
= 160·1.002
= 160.32
Периметр:
P = a + b + c
= 9.226 + 160 + 160.32
= 329.55
Площадь:
p =
S =√p·(p-a)·(p-b)·(p-c)
=√164.77·(164.77-9.226)·(164.77-160)·(164.77-160.32)
=√164.77 · 155.544 · 4.77 · 4.45
=√544013.64755532
= 737.57
