Answer:
x-2
Step-by-step explanation:
Answer: B
Step-by-step explanation:
Reflection does preserve side length and dilation preserves angles.
Look at the picture.
Corresponding Angles are equal.
Alternate Angles are equal.
Consecutive Angles add up to 180°.
----------------------------------------------------------------------
3a and 45 are Consecutive Angles. Therefore
3a + 45 = 180 |subtract 45 from both sides
3a = 135 |divide both sides by 3
<h3>a = 45.</h3>
----------------------------------------------------------------------
(2c - 1) and 45 are Corresponding Angles. Therefore
2c - 1 = 45 |add 1 to both sides
2c = 46 |divide both sides by 2
<h3>c = 23.</h3>
----------------------------------------------------------------------
3a and (12b + 3) are Alternate Angles. Therefore
3(45) = 12b + 3
135 = 12b + 3 |subtract 3 from both sides
132 = 12b |divide both sides by 12
<h3>b = 11.</h3>
Answer:
the two options that are equivalent would be the first option and the fourth option. (2x . 2y = 4xy) (5xyz = 5 . x . y . z)
