Aldo and Maya are standing on a riverbank, 220 meters apart, at points \( A \) and \( B \) respectively. (See the figure below.) Maya is 240 meters from a house located across the river at point \( C \). Suppose that angle \( A \) (angle \( B A C \) ) is \( 40^{\circ} \). What is the measure of angle \( B \) (angle \( A B C \) )? Round your answer to the nearest tenth of a degree.
