Yo thanks dude for the 25 point it’s generous :)
Answer:
38 degrees
Step-by-step explanation:
The angle can be found using the Law of Cosines:
a² = b² +c² -2bc·cos(A)
cos(A) = (b² +c² -a²)/(2bc) = (3² +7² -5²)/(2·3·7) = 33/42
A = arccos(33/42) ≈ 38.213°
The measure of angle A is about 38°.

just add them together :)
Answer:
The correct option is C.
Step-by-step explanation:
Two figures are congruent if their corresponding sides are congruent.
We know that, reflection, rotation and translation are rigid transformation. It means the size and shape of image and preimage are same. We can say that in rigid transformation, the image and preimage are congruent.
Dilation is not a rigid transformation. It represents enlargement and compression.
If scale factor |k|>1, then it represent enlargement. If scale factor |k|<1, then it represent compression.
In option C, the scale factor is 4. It means the sides of image are 4 times of the preimage.
Therefore option C is correct and the resultant figure of option C is not congruent to the original figure.
