Answer:
36
Step-by-step explanation:
[tex]\angle AOC[/tex] is made up of s + r, and since r is [tex]\frac{3}{5}[/tex] of [tex]\angle AOC[/tex] we know r must be the remaining [tex]\frac{2}{5}[/tex] of [tex]\angle AOC[/tex].
We can solve for [tex]\angle AOC[/tex] by using this equation:
[tex]\frac{2}{5}\angle AOC = 24\\(\frac{2}{5}\angle AOC)\frac{5}{2} = (24)\frac{5}{2}\\ \boxed{\angle AOC = 60}[/tex]
1. 2 fifths of [tex]\angle AOC[/tex] is 24
2. multiply both sides by [tex]\frac{5}{2}[/tex] to isolate [tex]\angle AOC[/tex]
3. [tex]\angle AOC[/tex] is 60°
We can now solve for r
[tex]r = \frac{3}{5}\angle AOC\\r = \frac{3}{5}(60)\\\boxed{r = 36}[/tex]
1. the equation the problem gave us
2. substitute [tex]\angle AOC[/tex] for 60 (we solved for it before)
3. [tex]r[/tex] is 36°
