Question

Find the length of CA to the nearest tenth of a foot

Answer 1

Answer:

CA ≈ 3.1 ft

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan40° = $\frac{opposite}{adjacent}$ = $\frac{BC}{CA}$ = $\frac{2.6}{CA}$ ( multiply both sides by CA )

CA × tan40° = 2.6 ( divide both sides by tan40° )

CA = $\frac{2.6}{tan40}$ ≈ 3.1 ft ( to the nearest tenth )
