Answer:
a = 9.849
b = 20.25
c = 491.03
Step-by-step explanation:
By using Pythagoras theorem in the right triangle BDC,
(Hypotenuse)² = (Leg 1)² + (Leg 2)²
BC² = BD² + DC²
a² = 9² + 4²
a = 
a = 
a = 9.8489
a ≈ 9.849 units
By mean proportional theorem,
AD × DC = BD²
b × 4 = 9²
b = 
b = 20.25 units
BY Pythagoras theorem in ΔADB,
AB² = AD² + BD²
c² = b² + 9²
c² = (20.25)² + 9²
c² = 410.0625 + 81
c = 491.0625
c = 491. 063 units
What are so random? You dont know why you have to put what? Lol XD
For this case, what we should know is that a polygon is a geometric figure with n sides that is closed. It is usually the union of straight lines.
On the other hand, in order to find the area of a figure, we need it to be closed.
Therefore, the edges of an area are confined by snap points.
Answer:
FALSE
