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

Answer:
9, 30, 27
Step-by-step explanation:
To find the perimeter, you must add up each side. In this scenario, we know that the perimeter is 66 feet. We also know the sides, which are n, 3n+3 and 4n-9.
So, we must add the sides to get 66 feet.
n+3n+3+4n-9=66
Combine like terms, and solve:
(n+3n+4n)+(3+-9)=66
8n+-6=66
8n-6=66
n=9
So if n=9, we can easily find the value of the other sides.
3(9)+3=30 feet.
4(9)-9=27 feet
So, the sides are 9, 30, and 27 feet (in order).

Answer : The total number of fossils at the museum are, 25
Step-by-step explanation :
As we are given that 60% of a museum’s fossils are from the Jurassic Period.
Let the total number of fossils at the museum be, 'x'
Given:
Number of fossils from the Jurassic period = 15
The % of a museum’s fossils are from the Jurassic Period = 60%
Thus, the expression will be:
By solving the term 'x' we get:
Thus, the total number of fossils at the museum are, 25
