Answer 1

Răspuns:

Explicație pas cu pas:

A = 25°30'

B = 31°42'

___________'

A + B = 25°30' + 31°42' = 56°72' = 57°12'

B - A = 31°42' - 25°30' = 6°12'

4*A = 4*25°30' = 100°120' = 102°

2*A + 4*B = 2*25°30' + 4*31°42' = 50°60' + 124°168' = 51° + 126°48'

= 177°48'

90° - A = 90° - 25°30' = 89°60' - 25°30' = 64°30'

5*(A : 2) = 5*(25°30' : 2) = 5*(24°90' : 2) = 5*12°45' = 60°225' = 63°45'

(4*B) : 3 = (4*31°42') : 3 = 124°168' : 3 = 123°228' : 3 = 41°76' = 42°16'
