What's a generic way to find x?

use a ruler

guess

please

>>8687338
you can't, those segments are all clearly a different length. Ergo there is no solution.

QED

What if it's in 3 dimensions and folded in such a way that makes all x's the same, just our perspective playing tricks

You need to specify what information is known.

For an isosceles triangle, you need at least two numbers - e.g. (base, height), (base, angle), (base, side), (side, height), etc.

You then need two numbers to determine where the point is in relation to the triangle.


Once you have those, the solution is trivial, and is left as an exercise for the reader.

Sides are known
green line length is known
o is known
internal angles are known

>>8687443
If the red line is parallel to side B then just use the sine rule

>>8687455
it is parallel but i only know one side length of the small triangle (green)

>>8687470
Yeah so use rule of sines.

>>8687512
Don't I need 2 sides and 2 angles?

>>8687403
No solution still, because the third dimensional component can be any number, you can only possibly find it in terms of the dimensions

>>8687521
No you need one side and two angles

a/sin(A) = b/sin(B)
