Find the length of side BC.<br> Give your answer to 3 significant figures.<br> C<br> A<br> 71°<br> B
Vikki [24]

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 sig. figs )
