This one's a challenging one...

OpenStudy (amistre64):

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

OpenStudy (anonymous):

y1 or y2? can this be applied for both?

OpenStudy (amistre64):

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"

OpenStudy (amistre64):

r = 46 that is ;)

OpenStudy (anonymous):

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

OpenStudy (anonymous):

y1=46sin(27)

OpenStudy (amistre64):

nah x1,y1 has an angle of 27

OpenStudy (amistre64):

x2,y2 is 27+27 = 54

OpenStudy (anonymous):

y2=46cos(36)

OpenStudy (amistre64):

it less confusing if you measure your ys in sins but you could do y2 that way as well

OpenStudy (anonymous):

how do i find x?

OpenStudy (amistre64):

x = r cos(a)

OpenStudy (anonymous):

52 cos (27)?

OpenStudy (anonymous):

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

OpenStudy (amistre64):

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

OpenStudy (amistre64):

ignore the stuff they put in there to distract you with

OpenStudy (anonymous):

Is it really challenging????

OpenStudy (amistre64):

it can be

OpenStudy (anonymous):

i'm sorry, im just terrible at math >-<

OpenStudy (anonymous):

how do i give you both the points?

OpenStudy (amistre64):

each name has a good answer option beside it if you like

OpenStudy (anonymous):

got it, thank you :D
