check all that apply: If cos theta = 15/17 then: a. tan theta = 8/15 b. csc theta = 17/15 c. sin theta = 15/8 d. sec theta = 17/815

thats cos
anonymous
  • anonymous
ok. so now you have to use a²+b²=c² to find the 3rd side
anonymous
  • anonymous
i get 8 for the other side
anonymous
  • anonymous
yes. so these are the formulas tan Θ = opposite/adjacent cot Θ = adjacent/opposite sin Θ = opposite/hypotenuse csc Θ = hypotenuse/opposite cos Θ = adjacent/hypotenuse sec Θ = hypotenuse/adjacent

a.
anonymous
  • anonymous
ok so the answers would just be A and D
anonymous
  • anonymous
oops sec is just supposed to be 17/15
anonymous
  • anonymous
then yes, A & D
