So the number of deliveries made is approximately
As a fraction it’s 9/10 and a decimal is 0.9
The missing figure is attached down
∠a and ∠e are corresponding angles ⇒ B
Step-by-step explanation:
In the attached figure
- AB is parallel to CD
- They are intersected by a transversal
∵ AB // CD and intersected by a transversal
∴ ∠a = ∠e ⇒ Corresponding angles
∴ ∠b = ∠f ⇒ Corresponding angles
∴ ∠c = ∠g ⇒ Corresponding angles
∴ ∠d = ∠h ⇒ Corresponding angles
∴ ∠c = ∠f ⇒ alternate interior
∴ ∠d = ∠e ⇒ alternate interior
∴ ∠a = ∠h ⇒ alternate exterior
∴ ∠b = ∠g ⇒ alternate exterior
∠a and ∠e are corresponding angles
