A ball is tossed between three friends. The first toss is 8.6 feet, the second is 5.8 feet , and the third toss is 7.5 feet, which takes the ball back to the starting point. What angles are formed by these tosses..Step by step explanation ..Please

The angles formed by the tosses are 79.45°, 59.02° and 41.53°

Explanation:

The three different tosses form a triangle with three different sides.

We have a triangle with sides of length 8.6, 5.8 and 7.5 feet.

Let x°, y° and z° be the three angles of a triangle

Using the Cosine Rule to find the measure of the angle opposite the side of length 8.6 feet:

We can now find another angle using the sine rule:

So the third angle would be

z =  180 - 79.45 - 59.02

z = 41.53°

Therefore, the three angles are 79.45°, 59.02° and 41.53°
