(B) The cosine function,$\cos 	heta$,is a trigonometric function that represents the ratio of the adjacent side to the hypotenuse in a right-angled triangle.At $	heta = 0^{\circ}$,$\cos 0^{\circ} = 1$.At $	heta = 90^{\circ}$,$\cos 90^{\circ} = 0$.As the angle $	heta$ increases from $0^{\circ}$ to $90^{\circ}$,the value of $\cos 	heta$ changes from $1$ to $0$.Since $1 > 0$,the value of $\cos 	heta$ decreases as $	heta$ increases in this interval.
