What is the length of BC? Round to the nearest tenth.

Answer:
BC ≈ 20.5 in
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos35° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{BC}{AB}[/tex] = [tex]\frac{BC}{25}[/tex] ( multiply both sides by 25 )
25 × cos35° = BC , thus
BC ≈ 20.5 in ( to the nearest tenth )
