Answer 2

Lei dos senos

I) c/sen 45 = a/sen30

x/√2/2 = a/1/2

√2/2 = 1/2 x

√2/2 / 1/ 2  = x

x = √2

II)

x/sen 30 = 5√2/ sen 45

x/ 1/2 = 5√2/ √2/2

√2/2 x = 5√2. 1/2

x = 5√2 / 2  / √2/2

x= 5

III)  a/ sen 120 = b/sen 45

     sen 120 = sen 60

     x/√3/2 = 150/ √2/2

x√2/2 = 150 √3/2

x= 150 √3/2 / √2/2

x=  150√6/2

x= 75 √6
