Answer:

BC ≈ 19.4 cm

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos71° = $\frac{adjacent}{hypotenuse}$ = $\frac{AB}{BC}$ = $\frac{6.3}{BC}$ ( multiply both sides by BC )

BC × cos71° = 6.3 ( divide both sides by cos71° )

BC = $\frac{6.3}{cos71}$ ≈ 19.4 cm ( to 3 significant figures )

yKpoI14uk [10]

Answer:

Jill's is the longest.

if jeffs is 0.9 times the length of jacks, his is lesser than jacks. e.g. 2×0.9=1.8. Jeff's will always be shorter. since we know Jacks is over 1, Jill's will always be taller because 2×1.08=2.16 or Jill's length.
