Answer:
pythagoras theorem
height ladder can reach on the wall = side a or b
13 feet = hyp
5 feet = side a or b (you choose which one it is)(but the equation still works ......................................the same)
13^2-5^2 = 144
√144 = 12
Right side of the equation:
cos ( A - B ) - cos ( A + B ) =
= cos A cos B + sin A sin B - ( cos A cos B - sin A sin B ) =
= cos A cos B + sin A sin B - cos A cos B + sin A sin B =
= 2 sin A sin B - left side of the equation ( correct )
Answer: D
Step-by-step explanation:
We know the midline is at y=40, so eliminate A and B.
The period is 160, so 
This eliminates option C, leaving us with D.
