- Wait patiently for a helper to come along.
- Once someone helps you, say thank you and close the thread with:
+close
- Feel free to nominate the person for helper of the week in #helper-nominations
- Do not ping the mods, unless someone is breaking the rules.
- If you're happy with the help you got here, and the server overall, you can contribute financially as well:
Use the sine theorem.
let the triangle be ABC
where AB = 12 units
BC = x units
draw a line from point B such that it makes a right angle with side AC at point D
now u get 2 triangles
ADB and BDC
in triangle ADC
use cos 60° to find length of BD
then in triangle BDC
use cos 45° to find length of x
ohh yeahh, sorry i didn't think about that!!
@clear ore this is a shorter way, use this

okay, thank you both!!!!
