Answer:
AAA
Step-by-step explanation:
If by this you mean perpendicular bisectors, then they would intersect at one point.
Answer:
Step-by-step explanation:
The midpoint is essentially a point with the average of the 2 x-coordinates and the 2 y-coordinates.
The formula is:
We are given two points: A (7,0) and B (0, 3). Remember points are written as (x, y).
Therefore,
Substitute the values into the formula.
Solve the numerators first.
The midpoint can be left like this because the fractions are reduced, but it can be written as decimals too.
Answer:
The height of the cliff is 31.17 feet.
Step-by-step explanation:
For better understanding of the solution see the attached figure :
Let the height of cliff be x feet.
In ΔABC and ΔDEC,
m∠ABC = m∠DEC = 90° (Angle made between the height and the ground is right angle)
∠ACB = ∠DCE ( Angle of reflection = Angle of incidence because N is normal )
So, By AA postulate of similarity of triangles, ΔABC ~ ΔDEC
Now as triangles are similar, their sides will be proportional to each other.
Hence, The height of the cliff is 31.17 feet
