Question

AB=6cm e senC = 0.2 , Determine :
O valor da hipotenusa
e o seno do angulo agudo oposto

Answer 1

sen C = 6/BC --> 0,2 = 6/BC --> 0,2BC = 6 --> BC = 6/0,2 --> BC = 60/2 --> BC = 30 (hip)
AB² = 30² - 6² --> AB² = 900 - 36 --> AB² = 864 --> AB = \/864 --> AB = 12\/6
sen B = 12\/6/30 --> sen B = 2\/6/5
