Answer:
The correct answer is 47 degrees.
Step-by-step explanation:
Use cosine.
cos(x)= adj/hyp
cos(x)=19/28
x=arccos(19/28)
Use a calculator
x is approximately 47 degrees.

Answer:
k=5
Step-by-step explanation:
step 1
Find the equation of the line f(x)
we have the points
(-4,0) and (-2,2)
<em>Find the slope m</em>
Find the equation of the line in point slope form
we have
substitute
Remember that
f(x)=y
so
step 2
Find the equation of the line g(x)
we have the points
(-4,0) and (-2,-10)
<em>Find the slope m</em>
Find the equation of the line in point slope form
we have
substitute
Remember that
g(x)=y
so
Remember that
------>
therefore
k=5
10^8=100000000
100000000x6.71=671,000,000
The awnser is 671,000,000
