how would u work thi sout if you dont know the angle between 8N and floor and also the angle between 12N and floor?

#

by using the fact that its in equilibrium

#

this is wat i tried to do

#

then got stuck

hollow flower Jun 20, 2023, 11:24 AM

#

diagram is perfect

#

i could use double angle formula to rewrite 12sin(6-alpha) but idk if thats gonna help in any way

#

12cosB=8cosA

signal juniper Jun 20, 2023, 11:24 AM

#

hollow flower 12cosB=8cosA

yes

hollow flower Jun 20, 2023, 11:25 AM

#

12sinB+8sinA=2g

#

then just solve simultaneously

#

hollow flower then just solve simultaneously

how would u tho

#

wait 1 sec ilemme try smth

#

nvm im stuck

#

#

and trhen wat

#

#

wat do i do after this

hollow flower Jun 20, 2023, 11:43 AM
