Tee Ball is similar to baseball, but the field is a diamond 40 ft square. The pitchers mound is positioned 25 ft from homeplate. Determine the distance from the pitchers mound to 3rd base.

Triangle sides 40 and 25 and included angle = 45 degrees. We want the side opposite the 45 degree angle

c^2 = a^2+b^2 - 2ab cos 45
c^2 = 40^2 + 25^2 - 2*40*25 (sqrt 2/2)
c^2 = 1600+625-1414 =810
c=28.5

To determine the distance from the pitcher's mound to 3rd base in Tee Ball, we need to use the dimensions given. We know that the field is a diamond 40 ft square, and the pitcher's mound is positioned 25 ft from home plate.

In a standard baseball field, the distance from home plate to 3rd base is 90 ft. However, since Tee Ball uses a smaller field, the distances are different.

To find the distance from the pitcher's mound to 3rd base, we can use the Pythagorean theorem. Since home plate, the pitcher's mound, and 3rd base form a right triangle, we can use the theorem to find the missing side.

The formula for the Pythagorean theorem is: a^2 + b^2 = c^2

In this case, a is the distance from home plate to 3rd base (90 ft in baseball), b is the distance from the pitcher's mound to home plate (25 ft), and c is the distance from the pitcher's mound to 3rd base (what we want to find).

Plugging in the values, we get:

c^2 = a^2 + b^2
c^2 = 90^2 + 25^2
c^2 = 8100 + 625
c^2 = 8725

Now we can solve for c by taking the square root of both sides:

c = sqrt(8725)
c ≈ 93.41 ft

Therefore, the distance from the pitcher's mound to 3rd base in Tee Ball is approximately 93.41 ft.
