(1) The court, without a jury, shall hear and determine the questions presented in the petition.
(2) The court shall order the proposed annexation to take place, notwithstanding the provisions of any other law of this state, if the evidence establishes that:
(a) essential municipal services and facilities are not available to the inhabitants of such territory;
(b) the municipality is physically and financially able to provide municipal services to the area sought to be annexed; and
(c) at least one-eighth of the aggregate external boundaries of the territory sought to be annexed is contiguous to the boundaries of the municipality.
