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.

Step-by-step explanation:

Answer:
A=2(1+2)a2
Step-by-step explanation:
The slope of this line is -3/4
In order to find this, we look for two points on the line and then use the slope formula. Two points that are on the line are (0, 2) and (4, -1). Plug these into the following formula.
m (slope) = (y2 - y1)/(x2 - x1)
m = (-1 - 2)/(4 - 0)
m = -3/4
Answer:
Step-by-step explanation:

50 is little away from 49 and 50 is far away from 64.

As 50 is closer to 49 the square root of 50 will be closer to 7 than 8 and so it should be just a little over 7
√50 ≈ 7.1
