Given that x = 5.4 m and 0 = 26°, work out BC rounded to 3 SF.
bagirrra123 [75]

Answer:

BC ≈ 4.85 m

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos26° = \frac{adjacent}{hypotenuse} = \frac{BC}{AC} = \frac{BC}{5.4} ( cross- multiply )

5.4 × cos26° = BC , then

BC ≈ 4.85 m ( to 3 s f )
