r=radius, and a =angle height of a hole (y) is simply: r sin(a) and the x part is: r cos(a)

y1 or y2? can this be applied for both?

this is applied to any hole that you need to find. r = 42 in this case from what I can tell, and you just have to keep an eye on your angles for the "a"

r = 46 that is ;)

so for x1, y1, for example, the angle is 36, correct? (just trying to make sure i'm understanding)

y1=46sin(27)

  • amistre64
nah x1,y1 has an angle of 27
amistre64
  • amistre64
x2,y2 is 27+27 = 54

y2=46cos(36)
amistre64
  • amistre64
it less confusing if you measure your ys in sins but you could do y2 that way as well

how do i find x?
amistre64
  • amistre64
x = r cos(a)

52 cos (27)?

x1=46cos(27) x2=46sin(36)

no, the hole hasnt moved from its original spot; the radius is still 46
