Answer:
29.0 kilometers
Step-by-step explanation:
From the figure attached,
Lookout station Running Deer is at A, Station Lazy Bear is at B and Fire is at C.
Bearing from Running deer to Fire is S38.4°E.
Therefore, m∠SAC = m∠ACB = 38.4°
Distance between the stations Running Deer and Lazy Beer = 18 km
From the given triangle ABC,
Sin(C) = =
Sin(38.4)° =
y =
y = 28.978 ≈ 29.0 km
Therefore, distance between Fire and Running deer is 29 kilometers.
Answer:
Length of grey rod is th of the white rod.
Step-by-step explanation:
Let the length of each black rod = b units
Length of 2 black rods = 2b
Length of each grey rod will be = g units
Length of 3 grey rods = 3g
Since, length of 2 black rods = length of 3 grey rods
2b = 3g ----- (1)
Length white rod = Length of 2 black rods + Length of 3 grey rods
w = 2b + 3g
From the equation (1),
w = 2b + 2b
= 4b
b =
Therefore, length of grey rod is th of the white rod .
