<PRE><B>Question 860424</B>
Use the sum-to-product formula to simplify the expression: 
If sin 44 degrees + sin 16 degrees = sin A degrees, 0 A = how many degrees. 

-----
2sin(60/2)cos(28/2) = sin(A)
2sin(30)*cos(14) = sin(A)
cos(14) = sin A
sin(A) = cos(90-A)
---------------------------
A = 90-14 = 76 degrees
