Yes, I've found such a problem on the Internet, too. The difference is crucial.

I will definitely bet if I find a way to solve geometrically.I am an amateur mathematician, and I am very interested in a geometric solution to this problem.Maybe we can and solve this problem.It does not seem like an easy task.

I can not put this task on this site and maybe someone will conclude it. It is an interesting site and I hope it will be solved.  In a geometric way

Maybe someone kind person will appear and solve this task in another way, thinking about a drawing is the main thing here is how to build a drawing. An interesting task is not easy

There seems to be no solution to this problem other than trigonometry

Which side should I build of equal length? Give me a hint and maybe I will build a drawing

Is a good idea and how do I relate this drawing to that task ??

I will now set a similar task

That's the solution to this

This task is similar to the previous task and how to do it that way in drawing that task help someone

New construction

It's a good idea but I could not think of how to draw it

Your opinion is clear. That is, without trigonometry we will not find another way.

I do not know how to draw a picture, if someone can bet, maybe we can not do anything

The trigonometric solution was good, thank you for the help. But I was wondering if there was another solution. How to draw another option, give me a hint of a 66-degree equilateral triangle

If there is another way folks I wonder how to solve this task without trigonometry

Draw the sections CS from point B to point C and point C from point B so that the angle BS = CS and the angle SBC = SCB = 66 then how to proceed help me.

Okey

I think this problem can be solved by geometrical constructions rather than generically using sine rule, because the numbers, 48 and 18 degrees, have a specific property: on one hand, 48+18=66, on the other hand, 180-48=132=66x2 could be two angles of 66 degrees of an isosceles triangle with one angle of 48 degrees.

This is a good option, but how to build a magician's drawing is interesting

Yes, I did that, with the sine theorem, but in the end I can not solve it. Here I accept it

I do not know English well. I can not even understand what the equations are talking about. I used the sine theorem, I can not solve it completely and I wonder how you explain it.
