Răspuns:
m ( < O1) + m ( < O2) + m ( < O3) + m ( <O4) = 360 °
O2 = 3 × m ( < O1)
O3 = 3× m ( < O1 )
O4 = 4 × m ( < O1)
Inlocuim :
O1 + 3O1 + 3 O 1 + 4 O1 = 360 °
11 O1 = 360° 》
m ( < O1 ) = 360° :11
m ( < O1) = 32, 72
m ( < O2) = 3 × m ( < O1) = 3 ×32,72
m ( < O2) = 98,16
m ( < O3) = 98,16
m ( < O4 ) = 4 × m ( < O1)= 4× 32,72
= 130, 88
Poți converti aceste grade:
32, 72 = 33° 12'
98° 16'
130, 88 = 134° 28'
