do we know sine and cosine law

shy sphinx Jul 17, 2024, 6:22 AM

#

yeah use cosine theorem to find length of brace wire

#

then sine theorem to find angle at base of pole

#

then angle -90° gives the last one

Could you visual it for me

To find vertical off?

#

shy sphinx then angle -90° gives the last one

shy sphinx Jul 17, 2024, 6:57 AM

#

yes

#

c^2= a^2+b^2 -2abcos(C)

#

you find a^2 from this

#

which is the length of the wire

#

so a^2=c^2- b^2+2abcos(C)
