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 ?

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 ?
