Question

Need help with a math question

Answer 1

I can try. :)

Answer 2

I can help you !

Answer 3

Draw a rhombus. Label its vertices ABCD(I've done this). Angle A measures 160 degrees. Angle D measures x(x-1). Explain how to find the value of x.

Answer 4

any of you understand this?

Answer 5

first distribute

x(x-1)

Answer 6

okay, Ive drawn the rhombus and it looked just like that, but then I can
t figure out how to distribute it

Answer 7

x(x-1) =

x * x = ?

x * -1 = ?

Answer 8

x(x-1) = x^2 - x
x * x = x^2
x*-1 = -x

Answer 9

Correct

Answer 10

is that it?

Answer 11

\(x^2-x+160=180\)

Answer 12

\(x^2-x-20 = 0\)

Answer 13

2√5 ?

Answer 14

2√5x?

Answer 15

no, that isnt it nevermind.

Answer 16

How did you get that?

Answer 17

It should be like
\((x-?)(x+?)\)

Answer 18

He solved for it from here x^2−x+160=180

Answer 19

(x -5)(x +4) ?

Answer 20

Yes

Answer 21

correct

Answer 22

I dont understand where I go from here. This problem is really confusing to me.

Answer 23

I think it should be like
(x-5)(x+4)

x - 5 = 0

x + 4 = 0

and then you solve for x for both.

Answer 24

Or do something called x opp, and just change the signs.

Positive -> Negative

Negative -> Positive

Answer 25

(x = 5)
(x = -4)?

Answer 26

Right

Answer 27

You don't need parenthesis

just

x = 5

x = -4

Answer 28

okay

Answer 29

so it would look like this?
x(x-1)
5({-4} -1) = ...?

Answer 30

or would it be 2 separate problems? like,
-4(-4 - 1)
and
5(5-1)

Answer 31

x = 20 on both problems.. I feel dumb lol
