Answer:
157.5°
Step-by-step explanation:
Total size of interior angles=(2n-4)90°
(2x16-4)90= 2520
size of one interior angle= (2n-4)90°/n
2520/16
Answer= 157.5°
NB n is the number of sides
Answer: 44 I believe.

Not necessarily.
and
may be linearly dependent, so that their span forms a subspace of
that does not contain every vector in

For example, we could have
and
. Any vector
of the form
, where
, is impossible to obtain as a linear combination of these
and
, since
unless

The correct option is "d".
Given that L = 0.8T²
length of pendulum = 30ft
L= 0.8T²
30 = 0.8T²
T² = 30 / 0.8
T² = 37.5
T = √37.5 = 6.1 seconds
<span>So, 6.1 is the closest to the period in seconds for a pendulum that is 30 ft long.</span>
