tan = sin/cos
Answer by Boreal(15235) (Show Source): You can put this solution on YOUR website!
tangent x is sin x/cos x, here (5/7)/2 sqrt(6)/7; the 7 s in the denominator cancel each other.
5/2 sqrt (6); rationalize by multiplying numerator and denominator by sqrt (6)
5 sqrt (6)/12. ANSWER
numerically, it is 0.714/.7 or about 1.02.
5 sqrt (6)/12=1.02
