angles formed by these tosses are and
degrees to the nearest hundredth.
<u>Step-by-step explanation:</u>
Here , We have a triangle with sides of length 8.6 feet, 5.8 feet and 7.5 feet.
The Law of Cosines (also called the Cosine Rule) says:
Using the Cosine Rule to find the measure of the angle opposite the side of length 8.6 feet:
⇒
⇒
⇒
⇒
⇒
⇒
⇒
The Law of Sines (or Sine Rule) is very useful for solving triangles:
We can now find another angle using the sine rule:
⇒
⇒
⇒
So, the third angle =
Therefore, angles formed by these tosses are and
degrees to the nearest hundredth.
