Use a product-to-sum or sum-to-product identity to complete the simplification shown below.
sin(36 degrees)+sin(24 degrees)=sin(A)
where the exact value of A with 0 degrees < A < 90 degrees is:
***
cos(6)=sin(A)
cos(6)=sin(90-6)=sin(84)
sin(A)=sin(84)
A=84˚
..
calculator check:
sin(36)+sin(24)≈0.9945..
sin(A)=sin84≈0.9945..
