Answer: True, True, True
Step-by-step explanation:
A. True. Angles B and C are congruent, and since B' is congruent to B, by the transitive property, C is congruent to B', and thus has the same measure.
B. True. AB>BC, and the rigid motions won't change the side lengths.
C. True for the same reason in B.
13 + 3i
15 - 6i - 2 + 9i → Sum
collect like terms
(15 - 2) + ( - 6i + 9i) =13 + 3i
C. <2 is the correct answer
Answer:
B) n ≥ - 9 and n ≤ 1
Step-by-step explanation:
-3 <= n+6 <= 7
subtract 6 from all 3 sides
-3 -6 <= n+6 -6 <= 7-6
-9 <= n <= 1
Answer: 12
