Answer:
21.27 meters.
Step-by-step explanation:
Please find the attachment.
Let H and h represent height of building and tree respectively.
We have been given that a person on the ground looks up at an angle of 28° and sees the top of a tree and the top of a building aligned. The tree is 20 m away from the person and the building is 60 m away from the person.
We know that tangent relates opposite side of a right triangle with its adjacent side.
Similarly, we can find height of the tree.
Therefore, the difference in heights between the building and tree is 21.27 meters.
Answer: P = 6 miles
Step-by-step explanation: A rectangle is a quadrilateral with opposite sides with the same measure. As Central Park is one, its parallel sides has the same measurement.
Distance of points gives the measurement of the sides of the rectangle. It is calculated as:
For the first two points, (-1.25,-0.25) and (-1.25,0.25), note that x-components is the same, so, only y-component is relevant to the distance:
d = 0.5
Two sides of the rectangle are 0.5 miles.
For points (-1.25,0.25) and (1.25,0.25), y-component will add 0 to the formula. Then,
d = 2.5
Two sides of the park are 2.5 miles.
Perimeter is the sum of all the sides of a geometric figure.
Perimeter of central Park is
P = 0.5+0.5+2.5+2.5
P = 6
Central Park has perimeter of 6 miles.
