Answer: <em>S</em> ≈ 48.2°
Step-by-step explanation:
We can use trigonometry functions to solve.
Looking at angle <em>S</em>, t = 18 is the hypotenuse and r = 12 is the adjacent side. This means we can use the cosine function.



Its 23 all you have to do is times all the numbers around
False, you graph an open circle on -3 and shade to the right because x must be larger than -3 and it can not equal -3
