Sin in coxuan theorem Junior high school knowledge forgotten In triangle ABC, AC = 360 m, BC = 150 m ∠ B = 90 degree, find ∠ a


Using the theorem of positive metaphysics
The edge corresponding to ∠ B is AC
The edge corresponding to a is BC
(sin∠A)/BC=(sin∠B)/AC
sin∠A=(sin∠B)*BC/AC=1*150/360=5/12
∠A=arcsin(5/12)
