We present an explicit formula for angles between two subspaces of inner product spaces. Our formula serves as a correction for, as well as an extension of, the formula proposed by Risteski and Trenčevski [13]. As a consequence of our formula, a generalized Cauchy-Schwarz inequality is obtained. MSC 2000: 15A03, 51N20, 15A45, 15A21, 46B20
