Complete question
Daniel is 50.0 meters away from a building. Tip of the building makes an angle of 63.0° with the horizontal. What is the height of the building
CHECK THE ATTACHMENT
From the figure, using trigonometry
Tan(θ ) = opposite/adjacent
Where Angle (θ )= 63°
Opposite= X = height of the building
Adjacent= 50 m
Then substitute the values we have
Tan(63)= X/50
1.9626= X/50
X= 1.9626 × 50
X= 98.13m
Hence, the height of the building is 98.13m
0.75 kilometer= 75000 centimeters
Velocity of Deidre and her dog is 2.11m/s.
<h3>What is velocity?</h3>
- Velocity is the rate of change of position of an object in a particular frame of reference
- Mathematically, velocity of an object = Displacement of the object/time taken
<h3>What is velocity of Deidre and her dog ?</h3>
- The distance covered by Deidre and her dog is 95 meter towards north.
- The time taken to cover the distance is 45 second.
- So velocity of Deidre and her dog =95/45
=2.11m/s
Thus , we can conclude that the velocity of Deidre and her dog is 2.11 m/s towards north .
