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
I think the equation would be<span> x^2 + y^2 + Dx + Ey + F = <span>0</span></span>
6,782 is the nearest root.
The nearest integer would be 7.
I really hope this helped you! c:
Answer:
Intersection is what they both have in common.
In this case intersection of E and B is 3 and 8.
While the union is both of them added together.
Hope this helps

Answer:
$2,128
Step-by-step explanation:
6% + 6% = 12%
12% x 1900 = 228
1900 + 228 = 2128
her accoun balance will be $2128 after 2 years
