What is BC? Given ABC is a right triangle with right angle C? AC= 15 centimeters and m

Answer:
BC ≈ 12.6 cm
Step-by-step explanation:
Since the triangle is right use the tangent ratio to find BC
tan40° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{BC}{15}[/tex]
Multiply both sides by 15
15 × tan40° = BC, hence
BC ≈ 12.6 cm ( to 1 dec. place )
