Answer:
dimension is 5cm * 4 cm
Step-by-step explanation:
As the plane is parallel to the base, the ratio between plane's length and width is equal to the ratio of that of the base. -> similar shape.
Moreover, it also divided the rectangular prism into 2 smaller rectangular prism. hence the plane is identical to the base. Hence, same dimension.

Answer:
-9 is your answer for b.
Step-by-step explanation:
Note the equal sign, what you do to one side, you do to the other. Also note the rule that if you have a positive sign & a negative sign next to each other, the resulting sign would be negative:
b + (-17) = -26
b - 17 = -26
Isolate the variable (b). Add 17 to both sides:
b - 17 (+17) = -26 (+17)
b = -26 + 17
Simplify:
b = -26 + 17
b = -9
-9 is your answer for b.

Remember the rules:
Addition sign + Positive number = Add (Ex: 7 + 7 = 14)
Addition sign + Negative number = Subtract (Ex: 7 + (-7) = 7 - 7 = 0)
Subtraction sign + Positive number = Subtract (Ex: -3 + 4 = 4 - 3 = 1)
Subtraction sign + Subtraction sign = Add (Ex: 5 - (-5) = 5 + 5 = 10)

Answer:
65 degrees
Step-by-step explanation:
We are to find the angle formed by the support wire and the ground given the adjacent side and the hypotenuse
to find the angle, use cos^-1
(15/35) = 64.62
65 to the nearest degree
Answer:
A'B'= 34 units long.
Step-by-step explanation:
The length A'B' will be 2 times the length of AB.
AD = sqrt( (8-0)^2 + (8- -7)^2 )
= sqrt 289
= 17
So A'B' = 34 .
The total length needed to outline the shaded green part is 7.25 feet if the angle of green arc is 75 degree.
<h3>What is a circle?</h3>
It is defined as the combination of points that, and every point has an equal distance from a fixed point (called the center of a circle).
We know the perimeter of the sector is:
P = Arc length + radius + radius
To find how many feet will be needed to outline the shaded green part, first we find the green plus clear glass and subtract then only clear glass and find the difference.
Here, for outer diameter d = 12 feet and outer radius = 6 feet
For inner diameter = 6 feet and inner radius = 3 feet
θ = 75°
The outline needed for the green part:
= 14.5 - 7.25
= 7.25 feet
Thus, the total length needed to outline the shaded green part is 7.25 feet if the angle of green arc is 75 degree.
