Answer:
AC = 25
Step-by-step explanation:
Since ∠A = ∠C then the triangle is isosceles, thus BC and AB are congruent, that is
BC = AB, substitute values
7x - 1 = 5x + 5 ( subtract 5x from both sides )
2x - 1 = 5 ( add 1 to both sides )
2x = 6 ( divide both sides by 2 )
x = 3
Hence
AC = 6x + 7 = (6 × 3) + 7 = 18 + 7 = 25
