Hunter-Best [27]

Answer:

x = 28.60 feet

Step-by-step explanation:

We are given a height of 2 feet above the ground and the angle of elevation of 86 degrees. 

Now, let's assume that the form of our problem is in the form of a right triangle, we can solve for the remaining angle as follows;

180 - (90+86) = 4 degrees

The distance from the home plate to the centerfield is been calculated below as

2/sin 4 = x / sin 86

solving for x we have

x = 28.60 feet

We have 28.60 feet as our answer
