Answer:
279 feet
Step-by-step explanation:
To find x, we solve using the Trigonometric function of Tangent
tan θ = Opposite/ Adjacent
θ = 64°
Length of the shadow = Adjacent = 136 feet
Height of the building = Opposite = h
Hence,
tan 64 = h/136 feet
Cross Multiply
h = tan 64 × 136 feet
h = 278.84132245 feet
Approximately, h to the nearest foot ≈ 279 feet
Therefore, the height of the building = 279 feet
Answer:
1) x+10
2) 1/2
Step-by-step explanation:
Area of Rectangle = Width × Length
Area = 600 Sq ft
Width = 20
Length = L
20L = 600
L = 600/20 = 30
Floor is 30' long
Answer:
60.73cm
Step-by-step explanation:
10cm=diameter so raduis of circle=5cm
area of full circle=78.5398...
area of semicircle=39.2699...
area of square=100cm
100-39.26990817=60.73 cm
