Find the measures of the angles of the triangle whose vertices are A=(-2,0), B=(2,3), and C=(2, -3). The measure of ZABC is. (Round to the nearest thousandth.) A water main is to be constructed with a 12.5% grade in the north direction and a 20% grade in the east direction. Determine the angle @ required in the water main for the turn from north to east. 0= 1.5954 radians (Type your answer in radians. Round to the nearest hundredth as needed.)
