Scalars and vectors — practice question

A force $F$ is acting at an angle $\theta$ above the horizontal. What are its horizontal component and its vertical component?

• Ahorizontal component: $F \cos \theta$, vertical component: $F \cos (90^\circ - \theta)$
• Bhorizontal component: $F \cos \theta$, vertical component: $F \sin (90^\circ - \theta)$
• Chorizontal component: $F \sin \theta$, vertical component: $F \cos \theta$
• Dhorizontal component: $F \sin \theta$, vertical component: $F \cos (90^\circ - \theta)$
