Answer: r = 1

Step-by-step explanation:

The slope of a line can be represented as $\frac{y_2-y_1}{x_2-x_1}$ . Plugging in the following values would provide you with:

$\frac{(r)-(-5)}{(5)-(2)} =2$

$\frac{r + 5}{3} = 2$

$r + 5 = 6$

$r = 1$

Hope it helps :) and let me know if you want me to elaborate on anything.

The sin <ABC means that AC/AB. So we know AB=34. AC/AB=8/17. So the length of AC is 16. cos<ABC means BC/AB. tan<ABC means AC/BC.
