Answer:
B. 0.5 and 0.2
C 2 and 3.2
Step-by-step explanation:
because anything lesser than the standard value of one is smaller.
because anything over the standard value of one is larger.
As the question say this problem is a practice of the law of cosines!
The law of cosine: c^2=a^2+b^2-2ab*cos*c for any side a, b and c
The law can also be written as c=sqrt(a^2+b^2-2abcosc)
Now use this formula!(note cos 100 degrees is about 0.8623)
c=sqrt(15^2+16^2-2*15*16*cos100)
solving this we can MN is about 23.75
Round this to the nearest tenths now!
We get 23.8!
Thus the answer is D

Answer:

Step-by-step explanation:

compare with that y=mx+c
where m=slope .
So after comparing we get m=
As the lines are perpendicular


therefore m2=
Now from the equation
this equation passing to the point (-5,5) with m=

Therefore equation is
