Answer :
The 250 and 150 yards and the 100° angle are two sides and included
angle of a triangle. The third side by cosine law as 313.087 yards.
Response:
- 313.087 yards
How can the distance between the two locations be calculated?
The given parameters are;
Distance travelled on first hit = 250 yards
Distance travelled on second hit = 150 yards
Angle between the two hits = 100°
Required:
The distance the golfer is required to originally hit the ball to travel the
same location on the green.
Solution:
According to cosine law, we have;
d² = 250² + 150² - 2 × 250 × 150 × cos(100°)
Where;
d = The distance between the initial and location on the green
Which gives;
d = √(250² + 150² - 250 × 150 × cos(100 Degrees)) ≈ 313.087
The distance the golfer has to originally hit the ball for it to go directly to
the same position on the green is, d ≈ 313.087
- The correct option is the option 313.087 yards
