Answer:
180-90=90
90÷2=45
answer is 45
Step-by-step explanation:
To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.
I think you meant to write 
If so, then the answer is Choice A. {15, 16, 17, 18, ..., 50}
We simply list every natural number from 15 to 50, including both endpoints. The three dots mean "continue this pattern". This way we don't literally have to write out every single value (there are 50-15+1 = 36 values in this set).
Note: the set of natural numbers is {1,2,3,...} so a natural number is basically a whole number, but 0 is not included. Negative values aren't included either.
Answer:
45?
Step-by-step explanation:
Step-by-step explanation:
We have, a sphere and a cylinder have the same radius and height. The volume of the cylinder, 
The volume of sphere is : 
The volume of cylinder is : 
Dividing the volume of sphere and the volume and cylinder, such that,

As r = h

So, the volume of sphere is (four-third) of 11. therefore, the correct option is (A).
