Question

2. Solve for x. Round answer to the nearest tenth. *

Answer 1

Answer:

x ≈ 7.4

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos22° = $\frac{adjacent}{hypotenuse}$ = $\frac{x}{8}$

Multiply both sides by 8

8 × cos22° = x, thus

x ≈ 7.4 ( to the nearest tenth )
