Question

Find the largest angle in a triangle in which the sides are in the ratio 5:6:8

A golfer hits his ball B a distance of 170m on a hole H which measures 195m from the tee T to the green. If his shot is directed 10 degrees away from the true line to the hole, find the distance betweenhis ball and the hole.

Answer 1

1.) Use Law of cosines on the angle opposite to the 8.

8^2 = 5^2 + 6^2 - 2(5)(6) (cos A)

3 = -60 cos A

A = 92.9°

This is the largest angle

2.) I think this is a trick question. It says "A golfer hits his ball B a distance of 170m on a hole H," therefore the answer would be 0 m because his ball is on the hole.
