Identify BR rounded to the nearest tenth. HELP PLEASE!!
ahrayia [7]

Answer:

<h2>BR ≈ 49.0</h2>

Step-by-step explanation:

Use cosine:

cosine=\dfrac{adjacent}{hypotenuse}

We have

adjacent=42\\hypotenuse=BR\\\alpha=31^o

\cos31^o\approx0.8572

Substitute:

\dfrac{42}{BR}=0.8572

\dfrac{42}{BR}=\dfrac{8,572}{10,000}          <em>cross multiply</em>

8,572BR=420,000                <em>divide both sides by 8,572</em>

BR=\dfrac{420,000}{8,572}

BR\approx49.0
