Find AC , round all answers to the nearest tenth​

Mathematics
1 answer:
baherus [9]2 years ago
4 0

Answer:

AC = 14.0

Step-by-step explanation:

We know that this is a non-right triangle, so we must use either the law of sines or law of cosines to find AC.

We can find the measure of <C using 180 - (118 + 22) = 40

Since we only know one side and all the angles, we can use the law of sines:  \frac{a}{sin A}=\frac{b}{sin B}=\frac{c}{sin C}

\frac{24}{sin 40}=\frac{AC}{sin 22}

Solving for AC gives us AC = 13.986826, which we can round to 14.0

belka [17]

Answer: Mrs.Buller collects a 500-ml sample of seawater for her chemistry class, and it has 1.94% of chlorine, we have to determine the amount of chlorine in the sample:

\begin{gathered} C=\frac{1.94}{100}\times500=9.7ml \\ C=9.7ml \end{gathered}

Therefore the chlorine content in 500ml of water is 9.7ml.
