Answer:
Below
Step-by-step explanation:
To find surface area, you can just find the area of each side and add them up!
11 ft x 9 ft x 2 = 198 ft^2 (this is the surface area of the front and back)
12 ft x 9 ft x 2 = 216 ft^2 (this is the surface area of the sides)
12 ft x 11 ft x 2 = 264 ft^2 (this is the surface area of the top and bottom)
Surface area = 198 + 216 + 264
= 678 ft^2
Hope this helps! Best of luck <3
Answer:
x = 180 - 32 - 43 - 72 = 33°
Step-by-step explanation:
Substitute the x values from the table into the equation.
<u>Substitute -4 into the equation:</u>
y = -3(-4) + 4
y = 12 + 4
y = 16
<u>Substitute -2 into the equation:</u>
y = -3(-2) + 4
y = 6 + 4
y = 10
<u>Substitute 0 into the equation:</u>
y = -3(0) + 4
y = 0 + 4
y = 4
<u>Substitute 2 into the equation:</u>
y = -3(2) + 4
y = -6 + 4
y = -2
y = 16, 10, 4, -2
The points you are looking for are the midpoints of segments JL and JK.
J(-2, -1), K(4, -5), L(0, -5)
The midpoint of segment JL is
(-2 + 0)/2, (-1 + (-5))/2) = (-2/2, -6/2) = (-1, -3)
The midpoint of segment JK is
(-2 + 4)/2, (-1 + (-5))/2) = (2/2, -6/2) = (1, -3)
Answer: The coordinates are (-1, -3), (1, -3)
