Answer:
1) 24x-72; 2) 6x-18; 3) 2x-9
Step-by-step explanation:
You can divide it or multiply it by whatever number it is to make it a whole number, not a decimal. Or else it will be even more difficult.
Okay, the answer would be.
tan60=p/b
tan60=12/x
x=37.5
now taking sin
sin60=p/h
sin60=12/y
y=(-40) but as length can be negative so
y=40
V=d/t=522/9=58
t=d/V=638/58=11h
