someone can help me

a

In the grafic, get "x"

[tribal crown]

sum of angles of a quadrilateral is 360

how can you use this fact?

[astral fog]

2a+20 + 220 + x = 360?

[tribal crown]

where did you get 20 and 220

or is that 2 $\theta$

@astral fog

[dapper reef]

[tribal crown]

if its $2\theta$ then youre very close to the correct track

[tribal crown]

however you have three variables and you need to find more possible equationsn

[astral fog]

Is it

I understand

wait

quadrilateral with fact 80 grades:
80+220+2a+ 2$\theta$ =360

[pulsar rune]

fene

[astral fog]

a= theta are same?

The angle

[tribal crown]

nope

you have three varaibles here

meaning you need three equations to solve for each

[astral fog]

but this is correct?

[tribal crown]

its close but

which quadrilateral is that equation for

[astral fog]

The another equation is x+a+theta= 360

[tribal crown]

like this one?

[astral fog]

yep

[tribal crown]

are the angles 2a or just a

[astral fog]

a

[tribal crown]

this is also wrong, check again

[astral fog]

I didnt check it

[astral fog]

For this, the equation is a+0+220+80=360?

[tribal crown]

yup

[astral fog]

and for the red is x+a+0=360

And for all quadrilateral 2a+ 2theta+ x+220= 360?

[tribal crown]

yup

wait no

red is wrong

youre missing an angle there

everything else is good tho

[astral fog]

+280*

[tribal crown]

nice

okay do you know how to do systems of simultanious equations

[astral fog]

yes i know

x+a+0+280= 2a+ 2theta+ x+220

If both are worth 360, I can match them, can't I?

[tribal crown]

yup

[astral fog]

x=20?

Match the two quadrilaterals, the green with the red and end in an "x+280=300".

[tribal crown]

i would recommend plugging in all the values for the systems youve found

like for a and theta

and then check if everything does sum to 360

[astral fog]

ok

[astral fog]

I have not been taught that yet, could you explain it to me please? I think I confused it with another topic

[tribal crown]

oh so like

solve the simultaneous equations for all values

then check if they actually work

its a very basic double check method i usually do to make sure

[astral fog]

Like this? x+a+theta+280=a+theta+220+80

what I did was to simplify theta and a

x+280=220+80

[tribal crown]

nono like

once you have the numerical values of a, theta, and x

plug them in

like replace the diagram with all the values

and see if it makes sense

[astral fog]

how

[tribal crown]

well you have x=20 right

now solve for a and theta

[astral fog]

ah

ok

i understand

[astral fog]

For red and green quadrilateral

Is it

300+theta+a=300+theta+a

[tribal crown]

uuhhh

have you found what a and theta are

[astral fog]

But how to get that?

[tribal crown]

solving simultaenous equations
