Answer:

{a universal set is a set which contains all objects, including itself}

Step-by-step explanation:

a) you will create two circle, crossing over each other, and shade both the "A" the "B" and the middle space.

b) (AUB) means the same thing as universal set, but its called union, infact if you draw this out in Venn Diagrams this will be the exact same as answer (a).

c) A n B : mean A 'intersection' with B, so here you will only shade the area where both circles meet.

d) i am not sure of this one, sorry

Sholpan [36]

Answer:

x=2.17

Step-by-step explanation:

x^2 +18x+81=-4

            -81  -81

x^2 +18x= -85

    /18       /18

x^2= -4.7

\sqrt{x^2}= \sqrt{-4.7}

x= 2.17

Determine the measure of each indicated angle. Show all necessary steps!
Mariana [72]

The measure of the unknown angle are; a) x = 89 degrees, b) p = 92 degrees.

<h3>What is the sum of all the angles of a regular polygon?</h3>

For a regular polygon of any number of sides, the sum of its exterior angle is 360°.

We already know that a 4-sided polygon's angles add up to 360 degrees.

So to find the value of x:

69 + 118 + 84 + x = 360

x = 360 - (69 + 118 + 84)

x = 89 degrees

b)

For a 4-sided polygon, we also know that the outside angles add up to 360 degrees.

So to find the value of p:

100 + 62 + 106 + p = 360

p = 360 - (100 + 62 + 106)

p = 92 degrees
