Question

4/5 HELP! Find the missing side. Round to the nearest tenth

Answer 1

Answer:

x ≈ 18.9

Step-by-step explanation:

using the cosine ratio in the right triangle

cos19° = $\frac{adjacent}{hypotenuse}$ = $\frac{x}{20}$ ( multiply both sides by 20 )

20 × cos19° = x , then

x ≈ 18.9 ( to the nearest tenth )
