Answer:
A. A linear pair is two adjacent, supplementary angles.
Step-by-step explanation:
from the description,
< ABD = , so that;
< ABD + <DBC =
+ <DBC =
<DBC = -
=
Thus,
<FBE = < ABD = (vertically opposite angles)
<ABF + <FBE = (supplementary angles)
<ABF + =
<ABF = -
=
The statement that justifies why <ABF measures is a linear pair is two adjacent, supplementary angles.
Answer: 30
Step-by-step explanation: 6 factors as 3 × 2 and 5 doesn't factor. When finding the least common multiple, we're looking for factors that match up and here we have no factors that match up. This means that our least common multiple or <em>lcm</em> is simply 3 × 2 × 5 or 6 × 5 which is 30.
