Find MN to the nearest tenth?<br><br> A. 11.34<br> B. 16.1<br> C. 39.6<br> D. 23.8
Nana76 [90]

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

Find the area of the figure.
Gelneren [198K]

Answer:

64 + 28 = 92

Step-by-step explanation:

Split the figure in half creating two triangles and a square.

length and width for the square would be 8ft and 8ft. Multiply both for 64 to be the area.

7ft and 4ft are the height and base for the triangles.

In this case, just multiple 7 and 4 because normally you would need to divide the product by 2 however since there are two triangles it negates the step.
