Answer:
36.4 m
Step-by-step explanation:
Rounded to tenths, the dimensions are ...
12.7 m by 5.5 m
The sum of these is 18.2 m, so the estimate of the perimeter is ...
2·18.2 = 36.4 m
_____
The perimeter formula is ...
P = 2(L +W) . . . . . twice the sum of length and width.
Answer:
From the graph attached, we know that
by the corresponding angle theorem, this theorem is about all angles that derive form the intersection of one transversal line with a pair of parallels. Specifically, corresponding angles are those which are placed at the same side of the transversal, one interior to parallels, one exterior to parallels, like
and
.
We also know that, by definition of linear pair postulate,
and
are linear pair. Linear pair postulate is a math concept that defines two angles that are adjacent and for a straight angle, which is equal to 180°.
They are supplementary by the definition of supplementary angles. This definition states that angles which sum 180° are supplementary, and we found that
and
together are 180°, because they are on a straight angle. That is, 
If we substitute
for
, we have
, which means that
and
are also supplementary by definition.
