What is Perimeter of triangle ABC?
2 answers:
Considering they are congruent
if 7x-19=2x+11
how much is 6x-8
7x-19=2x+11
7x=2x+30
7x-2x=30
5x=30
X=6
6x-8=
(6*X)-8=
(6*6)-8=
36-8=
28
therefore
BC= 28
2x+11
(2*6)+11
12+11
23
23+28+24=75
therefore the perimeter is 75

ΔABC and ΔFEG are congruent. Therefore we have the equation:
7x - 19 = 2x + 11 <em>add 19 to both sides</em>
7x = 2x + 30 <em>subtract 2x from both sides</em>
5x = 30 <em>divide both sides by 5</em>
x = 6
AB = 24
AC = 2x + 11 → AC = 2(6) + 11 = 12 + 11 = 23
BC = 6x - 8 → BC = 6(6) - 8 = 36 - 8 = 28
The perimeter of ΔABC = 24 + 23 + 28 = 75
