answer: 6
Explanation:
hihi so the triangle in that picture is a isosceles triangle, you can tell from the angles, theyre both 63 degrees, meaning the two sides are equal.
first set up your equation and then solve
3x = 4x -2
-x = -2
x = 2
plug it in for AB
3(2) = 6
AB = 6
so your answer would be b !!
hope this helps !!!!
