Trigonometry, I don’t know how to find x.

Accepted Solution

Answer:Step-by-step explanation:I still suspect that Angle A is 30° and Angle B is 60°.  Otherwise the labels do not fit the illustration.If Angle A is 60°, as you insist, then the solution (the length of x) is as follows:                           opp side        xtan 60° = √3 = ---------------- = -----                           adj side          7Then:    √3            x-----------  =  -----      1              7Thru cross-multiplication we see that x = 7√3Multiply both sides by 7, which produces:7√3 = x
