Question

Calcule os valores de x e y, me ajudem por favor !

Answer 1

a) seno 30 = x/6  => 1/2 . 6 => x = 3
    cosseno 30 = y/6 => √3/2 . 6 => y = 6√3/2 = 3√2

b) seno 60 = x/8 => √3/2 . 8 => 8√3/2 = 4√3
    cosseno 60 = y/8 => 1/2 . 8 => 8/2 = 4

c) seno 45 = x/10 => √2/2 .10 => 10√2/2 = 5√2
    cosseno 45 = y/10 => √2/2 . 10 = 10√2/2 = 5√2
