p=perimeter of base
s=slant hight

anonymous · Answer

yes, i have that muich but I can't figure out how to calculate the slant height

anonymous · Answer

nevermind, i think i have it...by using 30-60-90 degree triangles I can use their theorems to figure out the lengths of the missing sides of both triangles, theremore finding the Hypotenuse of one triangle i find the slant height...
