Answer:
The image will be congruent to the pre-image because n=1
Step-by-step explanation:
The image dimensions are the original dimensions multiplied by the scale factor. If the scale factor is 1, the image is the same size as the original, hence congruent to the pre-image.
Find the mean of the following data set: 40, 58, 37, 23, 66, 42, 35, 37, 51, 42, 56, 37, 61, 52.

Answer:
45.5
Step-by-step explanation:
To find the mean is to find the average number of the data set.
In order to do this you add up all of the numbers, then divide it by the value how many numbers are in the set.
40+58+37+23+66+42+35+37+51+42+56+37+61+52= 637/14=45.5
Answer:
60
Step-by-step explanation:
We are given the triangles are congruent, that means the angles are the same measurement
<A = <X
<B = <Y
<C = <Z
We know A = 50 so X = 50
We know <Y = 70 so < B = 70
The three angles of a triangle add to 180
<A + <B + <C = 180
Substituting into the equation
50 + 70 + <C = 180
Combining like terms
120 + <C =180
Subtracting 120 from each side
120-120 +<C =180-120
<C = 60
