Answer:
All non-terminating decimals
Step-by-step explanation:A real number has to be written a fraction form
ex √2=1.41421356237
Those two angles have to add up to 180° as that is a straight angle, so 5x - 10 + 6x + 10 = 180. combine like terms to get 11x - 10 + 10 = 180. the 10 cancels, so 11x = 180. divide both sides by 11 to get x = approximately 16.36.
FYI - I CANNOT TELL IF THAT ACTUALLY SAYS 5
It's irrational.
An irrational number divided by a rational number will result in an irrational number
Volume of a Cylinder = πr²h
V = π * (11)² * 15
v = π * 121 * 15
v = 1815π units³
In short, Your Answer would be Option C
Hope this helps!
