Answer:
<em>x = 10</em>
Step-by-step explanation:
These angles are <em>same side interior angles</em>.
This means that (11x + 10) + (10x - 40) = 180
Solve for x:
11x + 10 + 10x - 40 = 180
21x - 30 = 180
+30 +30
21x = 210
/21 /21
<em>x = 10</em>
R = 60
60^2 * pi = 3600 * pi
angle = 30°
3600pi / 30 = 120pi
the answer is 120 * pi
Y=x. I hope that this helped! Good luck! :)
I can help what are the problems
Answer:
No for both
Step-by-step explanation:
If 2 x values that are the same but different y values for them then its not a function
