Answer:
cosine
Step-by-step explanation:
eliminate each ratio that will not work,
we'll just use Soh Cah Toa, which basically tells us when to use that ratio
Soh stands for sine=opposoite/hypotenuse
a sine ration would be the opposite side, but we are not given the opposite side, we are given the adjacent side, so we can eliminate this
Cah (correct answer)
Cah stands for cosine=adjacent/hypotenuse
x is the adjacent side to 27 degrees and we are given the hypotenuse, so this will work
Finally Toa won't work because
Toa stands for tangent=opposite/adjacent
We can automatically eliminate this because the tangent only uses the two legs, it does not use the hypotenuse
therefore our answer is the cosine ratio
