Answers:

sin(30)

1/2

============================================

Step-by-step explanation:

The trig identity we use is

sin(A+B) = sin(A)cos(B) + cos(A)sin(B)

In this case, A = 13 and B = 17

sin(A+B) = sin(A)cos(B) + cos(A)sin(B)

sin(13+17) = sin(13)cos(17) + cos(13)sin(17)

sin(30) = sin(13)cos(17) + cos(13)sin(17)

Use a calculator or the unit circle to determine that sin(30) = 1/2
