4x+40=180
4x=180-40
4x=140
x=35
angle A= 35°
angle B= 35(4)+40= 145°
Answer:
what is the question?
Step-by-step explanation:
The <em><u>correct answer</u></em> is:
pairs 2, 3, and 4
Explanation:
Congruent polygons are polygons that have the same size and the same shape. We can see from the diagram that the figure in pair 2 has been rotated to form the second figure in the pair. Since the shape and size were not changed, they are congruent.
The figure in pair 3 has also been rotated; this again preserves size and shape, so the figures are congruent.
The figure in pair 4 sees to have been reflected. This did not change the size or shape of the figure, so the pair is congruent.
Answer:
it may as well stay same or not move because of two equal forces acting on it
