Answer:

169 ft

Step-by-step explanation:

The law of cosines can be used to find the distance from the outfielder to the pitcher. It tells you for triangle ABC, the length of side c can be found from ...

c² = a² +b² -2ab·cos(C)

Here, we hve a=60.5, b=214, and C=36°. Then the desired distance is ...

c = √(60.5² +214² -2·60.5·214·cos(36°)) ≈ √28507.56 ≈ 168.84

The outfielder throws the ball about 169 feet.

Answer:

x = 3

Step-by-step explanation:

4(x+3) - x = x + 18

4x + 12 - x = x + 18

3x + 12 = x + 18

3x - x + 12 = x - x + 18

2x + 12 = 18

2x + 12 - 12 = 18 - 12

2x = 6

2x/2 = 6/2

x = 3
