Find the value of x. Round your answer to the nearest tenth. 10 19° x

Answer:
x ≈ 9.5
Step-by-step explanation:
using the cosine ratio in the right triangle
cos19° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{x}{10}[/tex] ( multiply both sides by 10 )
10 × cos19° = x , then
x ≈ 9.5 ( to the nearest tenth )
