By using <em>triangle</em> properties and the law of the cosine twice, we find that the distance between points M and N is approximately 9.8 meters.
<h3>How to determine the distance between two points</h3>
In this problem we must determine the distance between two points that are part of a triangle and we can take advantage of properties of triangles to find it. First, we determine the measure of angle L by the law of the cosine:

L ≈ 62.464°
Then, we get the distance between points M and N by the law of the cosine once again:

MN ≈ 9.8 m
By using <em>triangle</em> properties and the law of the cosine twice, we find that the distance between points M and N is approximately 9.8 meters.

Answer:
D or 176.71 inches squared.
Step-by-step explanation:
the radius is 7.5. put it in a calculator and you get D.
Sum of interior angles in a pentagon=540°
148+112+2x+2x+10+90=540
360+4x=540
4x=540-360
4x=180
x=180/4
x=45°
D. There is a 5/8 chance each time. You would multiply that together to get the answer seen in D.
