Question

6. Solve for x. Show all work and round to the nearest hundredth if necessary. 20 55°

Answer 1

Answer:

x ≈ 11.47

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos55° = $\frac{adjacent}{hypotenuse}$ = $\frac{x}{20}$ ( multiply both sides by 20 )

20 × cos55° = x , then

x ≈ 11.47 ( to the nearest hundredth )
