In the triangle ABC, given a = 8, B = 60, C = 75, find a, B,

In the triangle ABC, given a = 8, B = 60, C = 75, find a, B,

Make a line CD intersecting AB with D. the line is divided into two angles BCA, one is 30 degrees and the other is 45 degrees. It is easy to know that the angle CDA is a right angle. For these two triangles, one is a model of a straight triangle with 30 degrees and 60 degrees, and the other is an isosceles straight triangle with 45 degrees. It is easy to find out B = 8 / 2 radical 3 * radical 2 = 4 radical 6
