Right triangle ABC has three sides with lengths AB= 119, BC = 169, CA= 120. Find the value of cos C. hint: draw and label the tr
GenaCL600 [577]

Answer:

\cos(C)=\frac{120}{169}

Step-by-step explanation:

The triangle is shown in the attachment.

Recall that;

\cos(C)=\frac{Adjacent}{Hypotenuse}

This implies that;

\cos(C)=\frac{|AC|}{|BC|}

We substitute the values into the ratio to obtain

\cos(C)=\frac{120}{169}

How could you model 5 students sharing 4 bags of popcorn equally? How much will each student get?
Effectus [21]
Your answer is 0.8 or 80%
Explanation:

Consider the ratio written like a fraction:

<span><span>Count of sandwichescount of people</span>→<span>46</span></span>

But we need the count of sandwiches for 1 person. So we need to change the 6 people into 1 person. To change 6 into 1 divide it by 6

<span>6÷6=1</span>

For ratios, when multiplying or dividing, what we do to the bottomwe do to the top.

So to change <span>46</span> into what we want we apply

<span><span><span>4÷6</span><span>6÷6</span></span>=<span><span>23</span>1</span>← <span>Count of sandwichescount of people</span></span>

So each person ends up with <span>23</span> of a sandwich

<span>Now see where the shortcut comes from <span>46</span>=<span>23</span><span> of a sandwich</span></span>
