Step-by-step explanation:
Answer:
Amount of string let out by Jim will be 156.9 m.
Step-by-step explanation:
Distance between Jim and Patty = 200 m
Angle of elevation of the kite from Jim = 85°
Angle of elevation of the kite from Patty = 40°
Angle between the lines joining Jim and kite and Patty and the kite = 180° - (85 + 40)° = 55°
By applying Sine rule in the triangle formed by the kite, Jim and Patty,
x =
x = 156.94
≈ 156.9 m
Therefore, amount of string let out by Jim will be 156.9 m.
Scale factor: f=0.5
AB=2.2
LM=?
LM=f x AB=0.5 x 2.2 →LM=1.1
The length of LM is 1.1
