(adsbygoogle = window.adsbygoogle || []).push({}); which calculation should i use??@_@

1. The problem statement, all variables and given/known data

a 1.4 kg bottle of milk is lying horizontally in the rack. the two surfaces on which the bottle rest r 90^{0}apart, and the right surface makes an angle of 45^{0}with the respect to the ground. each surface exerts a force on the bottle that is perpedicular to the surface. determine the magnitude of each of these forces

* the bottle is lying 90 degree vertically

2. Relevant equations

f=ma?

w=mg?

or should i find the resultant force by using cos and sine

3. The attempt at a solution

ive tried..but all the answer are different..
