Question 847540: ABC is a triangle
angle ABC = BCA
length of side of AB is (3x - 5) cm
length of side AC is (19 - x) cm
length of side BC is 2x cm
work out the perimeter of the triangle and give the answer in cm please!

Since angles ABC and BCA are equal then sides AC and AB are equal
(3x - 5)=(19 - x)
4x=24
x=6
18-5=13 AB
19-6=13 AC
2*6=12 BC
13+13+12=38 cm
