Side length ttt is 6.436.436, point, 43 and sss is 5.395.395, point, 39. Given that \dfrac st \approx \tan(0.697) \approx \sin(0.994) \approx \cos(0.576) t s ​ ≈tan(0.697)≈sin(0.994)≈cos(0.576)st art fraction, s, divided by, t, end fraction, approximately equals, tangent, (, 0, point, 697, ), approximately equals, sine, (, 0, point, 994, ), approximately equals, cosine, (, 0, point, 576, ), approximately what is angle \betaβbeta in radians, to the nearest tenth?
