<em>Greetings from Brasil...</em>

According to the statement, one figure is scaled in relation to another, so we can apply similarity to polygons.....

So

BIG/small = BIG/small

or

small/BIG = small/BIG

12.5/10 = X/16

OR

10/12.5 = 16/X

12.5/10 = X/16

10X = 12.5 · 16

X = 200/10

<h3>X = 20</h3>

Could anyone give me the answer to this question?
love history [14]

Answer:

36

Step-by-step explanation:

\angle AOC is made up of s + r, and since r is \frac{3}{5} of \angle AOC we know r must be the remaining \frac{2}{5} of \angle AOC.

We can solve for \angle AOC by using this equation:

\frac{2}{5}\angle AOC = 24\\(\frac{2}{5}\angle AOC)\frac{5}{2} = (24)\frac{5}{2}\\ \boxed{\angle AOC = 60}

1. 2 fifths of  \angle AOC is 24

2. multiply both sides by \frac{5}{2} to isolate \angle AOC

3. \angle AOC is 60°

We can now solve for r

r = \frac{3}{5}\angle AOC\\r = \frac{3}{5}(60)\\\boxed{r = 36}

1. the equation the problem gave us

2. substitute \angle AOC for 60 (we solved for it before)

3. r is 36°
