Answer:
Option D) ∠B ≅ ∠D
Step-by-step explanation:
we know that
If two triangles are congruent, then the corresponding sides and the corresponding angles are congruent
so
If ΔABC ≅ ΔFDE
the corresponding angles are
∠A and ∠F
∠B and ∠D
∠C and ∠E
so
∠A ≅ ∠F
∠B ≅ ∠D
∠C ≅ ∠E
therefore
The statement that is true is ∠B ≅ ∠D
Substitute 8 for x in the function.
y=50(8)=400
He would travel 400 miles
They must sell 250 cameras
and 50 more cameras would be a $400 profit
Answer: Choice B
FH/FI = HG/IE
================================================
Explanation:
We're told that triangles EFI and GFH are similar. The order of the lettering is important because it tells us how the angles pair up.
- E and G pair up because they are the first letters of EFI and GFH
- F and F pair up as they are the second letters
- I and H pair up because they are the third letters
This means
Furthermore, it means
- EF corresponds to FG
- FI corresponds to FH
- IE corresponds to GH
Focus on the last two items of the list above. We can then form the proportion
FI/FH = IE/GH
which is the same as
FH/FI = GH/IE
when we apply the reciprocal to both sides. Since HG is the same as GH, we can then say
FH/FI = HG/IE
So basically the corresponding sides create equal ratios to form this proportion. There are many other proportions that can be formed.
