Answer:
106 m
Step-by-step explanation:
The law of sines is useful.
The angle opposite the given side of 50 m is ...
180° -83° -69° = 28°
Then the distance (d) opposite the 83° angle is ...
d/sin(83°) = (50 m)/sin(28°)
d = (sin(83°)/sin(28°))×(50 m) = 105.709 m
The ball is about 106 meters from the pin.
