It’s not that hard you just need to draw it.
Answer:
n=14
Step-by-step explanation:
To find the length of the given side with length "n", we must know the relationship between the different sections when the chords cross one another.
Now, the relationship we require is that when we multiply the 2 parts of both chords together, it will be equal to the product of the two sides in the other chord. Thus;
7(8) = 4(n)
56 = 4n
14 = n
A quadrilateral is said to be a parallelogram
1.Opposite sides are equal and parallel.
2. Diagonal bisect each other.
3. Opposite angles are equal.
It is given that , a Parrallelogram is graphed on a coordinate plane so the two points are in the first quadrant and two points are in the third quadrant.
Suppose ABCD is a Parallelogram.Then AB=CD and AD=BC.
Given, Vertices A,B lies in first Quadrant and Vertices C and D lies in Third Quadrant.Then Vertices of Parallelogram ABCD are
A=( x, y) and B=( y, x)
Then, C= (- x,- y) and D= (- y,- x), Arranged in Alphabetical order, that is A,B and C and D.
Pythagoran theorem
length of ladder=hyptonuse
height of window is one leg
distance base is fram building is other leg
a²+b²=c²
c=hyp
a and b are legs
18²+b²=20²
324+b²=400
b²=76
b=2√19ft or aprox8.7178ft
