As shown in the diagram, a ship sails 16 nautical miles east from a harbor. It then sails 18 nautical miles in the direction of

Tresset [83]

The angle between the legs of length 16 and 18 has measure 90 + 55 = 145 degrees.

Now use the law of cosines: it says $d$ satisfies

$d^2=16^2+18^2-2(16)(18)\cos145^\circ$

and solving for $d$ gives

$d=\sqrt{16^2+18^2-2(16)(18)\cos14^\circ}\implies d\approx32$

so the answer is C.

Find the area of the rectangle.

aev [14]

Answer:

$69y+23$

Step-by-step explanation:

The area of a rectangle will always be length times width or width times length, doesn't matter which way.

In this case, the width is $3y+1$ miles and the length is $23$ miles. So, the area is $23(3y+1)=23*3*y+23*1=69*y+23$ .

So, the area is $\boxed{69y+23}$ and we're done.
