Answer 2

sine the base angles of the triangle are equal, it means you have an isosceles triangle......an in an isosceles triangle, two sides are equal

Answer 3

since your base is below, then it means the other two sides are equal

Answer 4

well the triangle is isosceles... so the base angles are equal and the sides opposite the base angles are equal.

So you can say

3x = 4x - 2

jut solve for x..

when you know the value of x, you can find AB

Answer 5

with that said, you can say that
3x=4x -2
4x-3x =2
x=2

Answer 6

that isnt the right answer i check it and it wasnt right.

Answer 7

so after finding the value for x,
you can now substitute in the length of AB.....which is 3x .......so you then have 3 x 2=6

Answer 8

its 3x..so 3*2 = 6

Answer 9
