Tan(35)=x/12
x=12*tan(35)=8.40
Answer:
x=2
y=10.5
z=2.3
w=1.75
Step-by-step explanation:
both sides of each scale have the same weight attached to them so you just have to solve the following equasitions for each scale: 3x+1=7 2y+10=31 2z+2.2=6.7 4w+3/2=17/2
30 seconds, half a minute.
1) Add x to -2x, which is -x
2) Subtract 3 to 5, which is 2
