step 1: find objects weight by doing 9.81x10= 98kg (2s.f.)step 2: draw a triangle of forces about the object including all information you know e.g. 45 degree angle step 3: force down the slope use the equation mgsino which looks like 98 x sin45 = 69Nstep 4: find the reaction force with the equation mgcoso which looks like 98 x cos45 = 69N
