The distance between point on the ground from the top of the building is 396 meter, if the building is 280 m high and The angle of depression from the top of a building to a point on the ground is 45 degrees.
Step-by-step explanation:
The given is,
The angle of depression from the top of a building to a point on the ground is 45 degrees.
Height of the building is 280 meter.
Step: 1
Given diagram is a right angled diagram,
For right angle triangle,
90° = 45° + 45°
= 90°
Trignometric ratio,
sin ∅ = ....................(1)
For the above ratio take the bottom angle, that is angle of depression from the top of a building to a point on the ground is 45 degrees.
Where, Opp side = 280 meters
Hyp side = x
∅ = 45°
Equation (1) becomes,
sin 45° =
0.70710678 =
x =
x = 395.979
Distance between point on the ground from the top of the building, x ≅ 396 meter
Trignometric ratio,
cos ∅ =
Cos 45 =
Adj = (0.70710678)(396)
Bottom length, Adj = 280 meter
Result:
The distance between point on the ground from the top of the building is 396 meter.
Answer:
5.13
Step-by-step explanation:
Number of sampled workers= n= 1000
Percentage of residents favouring construction= p' = 60% = 60/100= 0.6.
Testing the claim that the percentage of people favouring the construction is more than 56%= p= 56/100 = 0.56.
To calculate the test statistics we use the formula below;
Test statistics= √n (p' - p)/ √[p×(1-p)] -----------(1).
Substituting the value into equation (1) above, we have;
Test statistics= √1000 (0.6-0.56) / √[0.56×(1-0.56)]
Test statistics= (31.62)(0.04) / √0.5(0.44) = 1.2648/ 0.2464
Test statistics= 5.13312
= 5.13 (to 2 decimal places)
