Question Details

Detailed explanation and options for the selected question.

If sin(A) = 3/5 and cos(B) = 5/13, where A and B are acute angles, what is sin(A+B)?

A. 56/65
B. 33/65
C. 32/65
D. 45/65

Explanation:

Using sin(A+B) = sin(A)cos(B) + cos(A)sin(B), substitute values and calculate sin(A+B) = 56/65. Other options are incorrect.
