Answer:
Rectangle A is not a scale drawing.
Rectangle B is a scale drawing.
Step-by-step explanation:
A scale drawing involves ratios.
Rectangle A:
10cm is double the original 5cm giving us a 1 : 2 ratio.
However, 25cm is <em>not</em> double the original 20cm. This means that this rectangle is not to scale of the given rectangle.
Rectangle B:
10cm is double the original 5cm giving us a 1 : 2 ratio once again.
This time however, 40cm is double the original 20cm. This means that this rectangle is a scale drawing of the given rectangle.

Answer:

Step-by-step explanation:

Answer:
a. 9 ft
b. 90 ° right angled
c. Right angle
d. 90°
e, Right angle
f. Angles on a straight line
g. 18 spots
Step-by-step explanation:
Here we have maximization question;
a. The separation distance of the dividing lines in a parking lot need to be far apart enough as to accommodate a vehicle with room to open the doors, therefore, it should be between 8.5 to 10 ft wide which gives a mean parking space width of approximately 9 ft
b. The angle of lines of the parking lot to the curb that will accommodate the most cars is 90°, because it reduces the width occupied by a car
c. The angle is right angled
d. Since the adjacent angle + calculated angle = angles on a straight line = 180 °
Therefore, adjacent angle = 90°
e. The angle is right angled
f. Angles on a straight line
g. The number of spots will be 162/9 = 18 spots.
Answer:
<h3>cosθ = c/√1+c²</h3>
Step-by-step explanation:
Given cot θ = c and 0 < θ < π/2
In trigonometry identity:
cotθ = 1/tanθ = c
1/tanθ = c
cross multiply
tanθ = 1/c
According to SOH, CAH, TOA:
Tanθ = opposite/adjacent = 1/c
cosθ = adjacent/hypotenuse
To get the hypotenuse, we will use the pythagoras theorem:
hyp² = opp²+adj²
hyp² = 1²+c²
hyp = √1+c²
Find cosθ in terms of c
cosθ = c/√1+c²
Hence the formula for cos θ in terms of c is cosθ = c/√1+c²
