Answer:
The vertical angles are angle AFE and angle BFD ⇒ 1st answer
Step-by-step explanation:
* <em>Lets explain when the vertical angle are formed</em>
- The vertical angle are formed wen two lines cross each other
- The vertical angles are opposite to each other
- The vertical angles are equal in measures
* <em>Look to the attached figure</em>
- There are three lines intersected at point F, line AD , line BE and
line FC
- Line AD intersects line BE at F
- Line FC intersects the two lines at F, where FC is between the sides
of the angle BFD
- <em>Lets find the vertical angles</em>
∵ Line AD intersects line BE at F
∴ <u><em>∠ AFE and ∠ BFD are vertical angles</em></u>
∴ <em>∠ AFB and ∠DFE are vertical angles</em>
∵ Line FC intersects the two lines AD and BE at point F
∵ The end point of line FC is F
∴ There is no vertical angles formed between the two lines and the
line FC
∴ The vertical angles are angle AFE and angle BFD
We have been given that a tree that measured feet tall was planted. A hundred years later, the tree is now
feet tall. We are asked to find the number of times times is tree now taller than it was when the school first opened.
To solve our given problem, we will divide present length of tree by length of tree when it was planted as:
First of all we will convert mixed fractions into improper fractions.
Now we will convert our division problem into multiplication problem by flipping the 2nd fraction as:
Cancel out common factors:
Therefore, the tree is is taller now than it was when the school first opened and option A is the correct choice.
