Start from the sum of the quadrilateral

#

write them in their form

#

both of triangle angle sum and quadrilateral's

dire bough
#

Idk

glacial mauve
#

you can't tell solution here lil bro

dire bough
#

Wdym

glacial mauve
#

but it's not 0

dire bough
#

Ok

#

But isn’t bottom left angle 180-2x-a

glacial mauve
dire bough
#

Oh

dire bough
#

360*

glacial mauve
dire bough
#

Wdym alpha

glacial mauve
#

a

#

like you said

dire bough
#

Ok

#

Why alpha

#

Is it a normal variable

glacial mauve
#

yes

dire bough
#

Isn’t bottom middle angle 180-x

#

So 360-(180-x+3x+a) is the bottom left angle

#

So why is it not 180-2x-a

dire bough
glacial mauve
#

it's the other angle not a

#

180-2x

#

bottom right

remote oracle
#

is the triangle isosceles?

nimble junco
#

360-(3x+a+180-x) + a = x

#

180-2x-a=x

#

a=180-3x

#

3x+a+180-x+ corner = 360 => 360-x+corner=360, corner =x

#

so x + a + 180-2x = 180 or -x + a = 0 or x=a

#

but as a=180-3x, x=180-3x, x=180/4

#

x=(25+20) = 45?

#

i dont even know what im did im sleep deprived sorry

glacial mauve
#

yes

#

but you can't solve it here

nimble junco
#

ok sorry
