                   b                                         -13

If we put them together, the expression formed is b - 13.

The expression that represents the number of cookies is b - 13.

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
