Answer:
C
Step by step explanation:
When you move a shape via rigid transformations, the dimensions of the shape do not change (by definition). This includes translation and rotation. Since the size or measure of any of the side lengths or angles is not changing when you move the shape, the only way that you can match one shape onto another with rigid transformations is if all of the corresponding sides and angles are congruent. Therefore, the correct answer is choice C. Hope this helps!
Answer : 2/5 I believe correct me if I'm wrong
Answer:
123 degrees
Step-by-step explanation:
Well, since we have a 4 sided figure, we know that the sum of the interior angles is 360 degrees.
(n-2)*180=(4-2)8180=360
Okay we are given 3 angles
120+43+74= 237
that means that x= 360-237
x=123 degrees
Answer:
anything below 136.5 or above 155.5
Step-by-step explanation:
the critical value from a Z distribution for the 99% confidence level is 2.576
so we just need to compute
146 + 2.576(34/sqrt(85))
and
146 + 2.576(34/sqrt(85))
