Answer:
x° = 54.5°
Step-by-step explanation:
The measure of angle x is half the difference of the intercepted arcs. The larger arc is shown as 141°. The smaller one must be computed from the arcs shown:
360° -187° -141° = 32°
So, the measure of x° is ...
x° = (141° -32°)/2
x° = 54.5°
we have the function

Part a
For t=7
substitute in the given function

For t=14

For t=21

For t=28

For t=35

Observation: The values of E varies from -1 to 1, including the zero
Part B
Remember that
The Period goes from one peak to the next
so
Period=2pi/B
B=pi/14
Period=(2pi)/(pi/14)=2pi*14/pi=28
<h2>the period is 28 days</h2>
Answer:
14
Step-by-step explanation:
We are given with two
numbers whose first
are same.
It is given that their sum is 
adding the last two corresponding digits gives,

Now adding the rest,
to get 
should not give anything to carry as that will make A in decimal to satisfy the addition.
Therefore,

Thus 
And finally,

Thus 
Now simplifying

Thus
is the answer.
