For number 5, if you know that one angle is 65 degrees, then you can find the angle of the supplementary angle by subtracting it from 180:

180 - 65 = 115 degrees < this is what your supplementary angle will be.

Starting from the top, the graph should read:

115 , 65
65 , 115
115 , 65
65 , 115  

For number 6, all of the angles are right angles. We know that all right angles have a degree of 90, therefore every angle should be written as 90 degrees. Additionally, in order to find any supplementary angle, you take the known (90) and subtract it from 180. >> 180 - 90 = 90.

I'm desperate. I need all of them answered
notsponge [240]

a. A' means the complement with respect to Z? If so, then

To know A' you need to write all the elements in Z that are not in A.

A'= \{ u, v, w, x, y, z\}

b. All the subsets of B, is knowed as P(B),

P(B) = \{ \emptyset, \{w\}, \{x\}, \{y\}, \{w,x\}, \{w,y\}, \{x,y\}, B \}

c. A \cup B = \{a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t, w,x,y \} (Add to A the elements of B, or equivalently add to B the elements of A)

d. A \cap B  express informally speaking the elements that have in common, but there is no element in common, so

A \cap B = \emptyset

PLEASE HELP IM SOOOO LOST ILL GIVE A BRAINLIEST TO THE BEST ANSWER THAT HAS ALL WORK SHOWN AND CORRECT ANSWERS AND MAKES SENSE.
Tanzania [10]
6(a+3) = 18 + 6a
Open the parenthesis and distribute
6a + 18 = 18 + 6a
Subtract both sides by 18
6a = 6a
Subtract both sides by 6a
0 = 0
Any value of "a" will satisfy this equation.
