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:
14 years old
Explanation:
Use this system of equations if G=George and J=Jeannie:
G-12=J
50=(G+5)+(J+5)
So, change second equation becomes
40-G=J
Then use substitution:
G-12=40-G
2G=52
G=26
Then, to find Jeannie’s age, go back to one of the equations and substitute G.
26-12=J
So, J=14
Jeannie is currently 14 years old.

Step-by-step explanation:
Please find the attachment.
We have been given that angle FED with angle F=90 degree, ED=36, and FE=22. We are asked to find the unknown angles and the unknown side length of the triangle.
We will use sine to solve for angle D as:





Therefore, measure of angle D is 37.7 degrees.
Now, we will find measure of angle E using angle sum property.





Therefore, measure of angle E is 52.3 degrees.
We will use Pythagoras theorem to solve for side FD as:







Therefore, length of side FD is approximately 28.5 units.
Answer:
Answer
0.109589 millimeters per day.
Explanation
10 mm = 1 cm
4 cm = 4 × 10
= 40 mm
365 days = 1 year
rate to millimeters per day = 40 mm in 365 days
= 40/365 mm/day
= 8/73 mm/day
or = 0.109589 mm/day.
Rate to millimeters per day = 0.109589 millimeters per day.

Step-by-step explanation:
The right triangle is isosceles, so x = 45° and tan(x) = 1.
__
You can determine tan(x) either from your knowledge of trig function values, or from the fact that the two legs of the triangle are of equal length. The tangent is the ratio of the opposite leg to the adjacent one. When those legs are the same, the ratio is 1.
