Answer:
B) m∠ A'B'C' = m∠ABC
Step-by-step explanation:
A rotation does not change angle measure or side length. It preserves congruence.
This means that the image angle, A'B'C', will be congruent to the pre-image angle, ABC.
Answer:
96
Step-by-step explanation:
40=4x+8
32=4x
x=8
other side x+4 is 12
area is 12×8
96
1:Replace the variables in the theorem with the values of the known sides.
2:Square the measures, and subtract from each side
3: find the square root of each side
Answer:
y = x + 2
Step-by-step explanation:
As the equation of a line is in the form y = mx + c:
Step 1 - Calculate the y intercept
This can be done by looking at the y coordinate where x = 0:
y = mx + c
In the picture, the y intercept is 2 so:
y = mx + 2
Step 2 - Calculate the slope
This can be calculated by:

Get two sets of coordinates:
(0, 2) and (2, 4)
Calculate the changes by subtracting from one another:

So the gradient is 1, meaning the equation of the line is:
