x is equal to 12.77 cm.
In order to find this, we need to use the sin function. Sin is equal to the opposite side divided by the hypotenuse. Therefore we can use the information we have and this to solve.
Sin(Angle) = Opp/Hyp
Sin(70) = 12/Hyp
HypSin(70) = 12
Hyp = 12/Sin(70)
Hyp = 12/.939
Hyp = 12.77
