Answer:
The dilation scale factor is .
Step-by-step explanation:
The image is the dilated form of its preimage if and only if the following conditions are observed:
1)
2)
3)
4)
5)
If we know that , , , , , , and , then the coefficients are, respectively:
, , ,
As , we conclude that the dilation scale factor applied in the preimage is equal to .
Answer:
∠A and ∠G is the pair of vertical angles.
Step-by-step explanation:
From the figure attached,
Two lines 'm' and 'n' are two parallel lines. These lines intersect a horizontal line 'l'.
Since, "Pair of opposite angles formed at the point of intersection are the vertical angles and equal in measure."
Therefore, Opposite angles ∠A ≅ ∠G, ∠B ≅ ∠H, ∠C ≅ ∠E and ∠D ∠F are the vertical angles.
From the given options,
∠A and ∠G is the pair representing the pair of vertical angles and thus congruent.
I think the answer to your question is 15 hope this helps
The formula for tan is opposite/adjacent.
This being said, 12/13 would equal approximately 0.923077.
Hope this helps. ^^
