Consider a right triangle A B C where the angle A is right and the angle B is α. Let M be the middle point of B C. Then, the angle A M C is 2 α. Now apply on the triangle A M C the law of sines: sin 2 α A C = sin ( 90 − α) 1 2 B C. Since A C = B C sin α and sin ( 90 − α) = cos α the identity follows. fixanker würth m12 https://livingpalmbeaches.com
