Answer:
1
Step-by-Step Explanation:
30° and 60° are angles of one of the standard triangles
sin (30°) = 1/2
cos(30°) = √3/2
sin(60°) = √3/2
cos(60°) = 1/2
So,
sin(60°) · cos(30°) + sin(30°) · cos(60°)
= (√3/2)(√3/2) + (1/2)(1/2) = 3/4 + 1/4
= 1
One of the conventional triangles' angles is 30 degrees and 60 degrees.
sin (30)= 1/2
cos (30)= √3/2
sin (60)= √3/2
cos (60)= 1/2
So, Sin (60)・cos (30) + sin (30) ・cos (60)
