Find the missing side lengths. Leave your answers as radicals in simplest form. Please help!! Due today
Nataly_w [17]

Answer:

m = 10\sqrt 3

n = 10

Step-by-step explanation:

Required

Find m and n

Considering the given angle, we have:

\sin(60) = \frac{Opposite}{Hypotenuse}

This gives:

\sin(60) = \frac{m}{20}

Make m ths subject

m = 20 * \sin(60)

\sin(60) =\frac{\sqrt 3}{2}

So, we have:

m = 20 *\frac{\sqrt 3}{2}

m = 10\sqrt 3

Considering the given angle again, we have:

\cos(60) = \frac{Adjacent}{Hypotenuse}

This gives:

\cos(60) = \frac{n}{20}

Make n the subject

n = 20 * \cos(60)

\sin(60) =\frac{1}{2}

So, we have:

n = 20 *\frac{1}{2}

n = 10

This is the same as ...

  total = 170/0.85 = 200

200 students were in the program.

_____

<em>Critical Thinking</em>

There are three declarative statements here. <em>There is no question</em>. We have made up a question to answer.

Another possible answer to the non-question could be, "The parent can ask his student how many students were in the program."

Pavel [41]
The answer is: 15

Because if for every 5 c cookies there is 3 oatmeal cookies, we can add 5+3=8. 40 divided by 8= 5. 5 times 3 equals 15. That’s why the answer is 15
