If all elements of set a are also elements of set b, then set a is a(n) of set b

The correct option is subset.

Step-by-step explanation:

If all elements of set A are also elements of set B, then set A is a(n) subset of set B

According to the definition of subset, A set A is a subset of another set B if all elements of the set A are elements of the set B. In other words, the set A is contained inside the set B. It is denoted by A⊆B.

For example:

A={1,2,3} B={1,2,3,4}

In this example A is a subset of B because all the elements of A  are elements of set B but set B has some extra element. Therefore A is a subset of B

Therefore according to the given explanation the correct option would be subset

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.

assuming you mean addition: addition and subtraction are reverse operations.
