jhonyy9 (jhonyy9):

this is an equilateral triangle - yes ?

OpenStudy (devonhoward15):

is it 8? i need the answer quick anyone plz

OpenStudy (devonhoward15):

yeah it is

jhonyy9 (jhonyy9):

so what mean this ? that every 3 angles are congruent - yes ?

OpenStudy (devonhoward15):

yes

OpenStudy (devonhoward15):

all sides are equal

jhonyy9 (jhonyy9):

and again that than you assume every 3 angles you need getting the result of 180 degree yes ?

OpenStudy (devonhoward15):

yes

jhonyy9 (jhonyy9):

so from this result that 3(7x+4) = 180 do you can calculi from this the value of x ?

jhonyy9 (jhonyy9):

distribute the parentheses so what will get ?

OpenStudy (devonhoward15):

my phone cant do that

jhonyy9 (jhonyy9):

3*7x= ?

OpenStudy (devonhoward15):

21x

jhonyy9 (jhonyy9):

yes 3*4=?

OpenStudy (devonhoward15):

12

jhonyy9 (jhonyy9):

ok. 21x +12 =180 21x = 180-12 180-12 = ?

OpenStudy (devonhoward15):

168

jhonyy9 (jhonyy9):

21x = 168 divide both sides by 21 what will get for x = ?

OpenStudy (devonhoward15):

8

jhonyy9 (jhonyy9):

21x 168 ----- = ------ 21 21 do you can continue it ?

jhonyy9 (jhonyy9):

yes exactly 8 x = 8 do you understand it now ?

OpenStudy (devonhoward15):

thanks

jhonyy9 (jhonyy9):
