Answer 1

x = 22

Explanation:

Since ∠ B = ∠ C then the triangle is isosceles with 2 legs congruent , that is

AC = AB , substitute values

2x - 24 = x - 2 ( subtract x from both sides )

x - 24 = - 2 ( add 24 to both sides )

x = 22

Answer 2

BC = 22

Explanation:

This is an isosceles triangle.

2x - 24 = x - 2

2x = x - 2 + 24

2x = x + 22

2x -x = 22

x = 22
