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>

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

$BR\approx49.0$
