Answer 1

@amistre64

Answer 2

how did you get that please show so i can learn

Answer 3

i take it that you are looking at that squashed up rectangle with a 118 on it?

Answer 4

yes

Answer 5

well, one property of squashed rectangles (parallelagrams) is that the sum of their angles is 360

Answer 6

360 - 118?

Answer 7

thats what i was thinking at first, but its simpler than that, the angle C is also 118, so we can work a triangle sum for the rest of it

Answer 8

the sum of the angles of a triangle are 180 so...

118 + (7x+4) + (5x-2) = 180

Answer 9

wow:) is that all i have to do for that problem?

Answer 10

yep

Answer 11

thank you:) can you help me with the one after that problem PLEASE

Answer 12

a rhombus us a squished square, so all the sides are the same length; what is the length of one side?

Answer 13

yes

Answer 14

s+s+s+s = 80, we need to determine the value of "s"

Answer 15

the pythag thrm will help us determine "y" but we first need to determine "s"

Answer 16

12 * 12?

Answer 17

there are 4 "s"ides, a perimeter is the measure of all the sides

s+s+s+s = 80, we need to determine the value of "s"

Answer 18

yes

Answer 19

"yes" is not a value of "s"

s+s+s+s = 80

4s = 80

what is s?

Answer 20

oh my apologies.

4 x 20

Answer 21

good, now we have something to work with :)

Answer 22

how would the pythag thrm help us solve for y ?

Answer 23

its a right triangle

Answer 24

itll give you what we need...which is y

Answer 25

a^2 + b^2 = c^2

Answer 26

good, let a = 12, b = y, and c = 20

Answer 27

12^2 + y^2 = 20^2

y^2 = 20^2 - 12^2

y = sqrt(20^2 - 12^2)

Answer 28

since y is half of the long diagonal, we need to double it for our answer

Answer 29

sq root 400 - 144 = 256

Answer 30

sq root 256

Answer 31

= 16

Answer 32

so far so good

Answer 33

r we done

Answer 34

nope, 16 is only half the length, we need to double it

Answer 35

16 times 16?

Answer 36

not quite, 16 + 16

Answer 37

nvm that wouldnt double it

Answer 38

ok

Answer 39

32

Answer 40

thats not doubling it

Answer 41

lets go with 32 for the win ;)

Answer 42

r u pranking me

Answer 43

doubling means making the number larger..

Answer 44

double means to make 2 times the amount

if you have 4 dollars and want to double it, then you want 8 dollars

Answer 45

twins are "doubled"

Answer 46

"duo" is a latin root for 2

Answer 47

good luck ;)

Answer 48

OHHHHHHHHHHHHH i forgot we did the sq root of 256

Answer 49

thank you

Answer 50

can you tell me what the last question asks:(
