You are the head of a building department . Your department is making final inspections of two types of new commercial buildings
--gas stations and restaurants . Final inspections involve the work of three separate inspectors : a plumbing inspector , an electrical inspector , and a building inspector . The plumbing inspector requires 4 hours to inspect a gas station and 2 hours to inspect a restaurant . The electrical inspector requires 2 hours to inspect a gas station and 6 hours to inspect a restaurant . The building inspector requires 4 hours to inspect a gas station and 6 hours to inspect a restaurant . Considering the time required for other duties , the plumbing inspector has 28 hours a week available for inspections ; the electrical inspector has 30 hours available and the building inspector has 36 hours available . You want to inspect as many commercial buildings as possible each week . Set up this problem as a linear programming problem .
An isosceles triangle has congruent base angles, so if one of the base angles measure 54 degrees, then the other base angle does, too. And a triangle measures up to 180 degrees. 180 = x + 2(54) 180 = x + 108 x = 72 So the answer is B) 72
