Answer:
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 x
tan 60° = √3 = ---------------- = -----
adj side 7
Then:
√3 x
----------- = -----
1 7
Thru cross-multiplication we see that x = 7√3
Multiply both sides by 7, which produces:
7√3 = x
