Then give exact values for sin 60, cos 60, and tan 60. Answer by KMST(1852)   (Show Source): You can put this solution on YOUR website!"In triangle ABC, angle A is a right angle, angle B measures 60 degrees." So ABC is a 30-60-90 triangle (because , , and are the angle measures). If A is the right angle, then BC (opposite o angle A) is the hypotenuse. AB and AC are legs of the right triangle. Consider an equilateral triangle> It has three angles and is split by each altitude into two congruent 30-60-90 triangles.9 (Call one of those angles, angle B). In each of those right triangles, the short leg is half as long as the hypotenuse (BC), so for the smallest angle . . And then,
