Answer: Area of Parallelogram is 28 units squared.
Step-by-step explanation:
Knowing, any two vector sides of a parallelogram sharing the same initial point, we can find the area of parallelogram that two vectors are shaping, using the cross product of these two vectors a×b, where the area is given by
Area= |a×b| ___ (1)
From the given points,we may choose any three of them such and find a two vector and expresses the sides of parallelogram " or one side and a diagonal of parallelogram" ,we may choose for example B ,C and D.
Moreover, we may choose point B, to be common point for the two sides " the initial point of two vector" thus we need to find vector BD and vector BC .

Answer:
128 ft
Step-by-step explanation:
The height of the tower above eye-height is related to the angle by ...
Tan = Opposite/Adjacent
tan(72°) = (tower height above eye height)/(40 ft)
tower height above eye height = (40 ft)×tan(72°) = 123 ft
Since eye height is 5 ft, the total height of the tower from the ground is ...
tower height = eye height + height above eye height
tower height = 5 ft + 123 ft
tower height = 128 ft
Answer:
2. Side length =9
Step-by-step explanation:
A square has all sides equal. and it has 4 sides, so 36 divided by 4 =9.
3.x squared =6
answer is x=3
square root both sides.
