Consider the sets below. -u {x|x is any color} -a {x|x is a color of the rainbow} -r {x|x is red, yellow, or blue} is r ⊂ a?

                 Yes R ⊂ A.

Step-by-step explanation:

We are given a set U as:

          --- U= {x| x is any color}

          --- A= {x| x is a color of the rainbow}

We know that a rainbow has seven colors named as VIBGYOR

where V-- Violet

           I-- Indigo

           B-- Blue

           G-- Green

           Y-- Yellow

           O-- Orange

            R-- Red

Also we are given R set as :

       -- R= {x|x is red, yellow or blue}

This means that R is contained in A since all the elements that belong to R also belongs to set A.

Hence, we may say:

       Yes  R ⊂ A

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
