Answer:
Step-by-step explanation:
Circles are all similar, and "the circumference divided by the diameter" produces the same value regardless of their radius. This value is the ratio of the circumference of a circle to its diameter and is called π (Pi).
Answer: The correct equation is the option A.)A = x(x − 4) − 0.5(8)(x − 4) − 4(8)
Step-by-step explanation:
To find the painted area of the theater room in square feet, the following steps must be followed:
1. Determine the area of the theater room
Length: x
Width: x-4
A (theater room) = x (x-4)
2. Determine the area of the right triangle
Height: x-4
Base: 8
A (right triangle) = 0.5 (8) (x-4)
3. Determine the area of the rectangle inside labeled closet
Length: 8
Width: 4
A (closet) = 8 (4)
4. The area to be painted will be the substraction between the total area of the theater room, less the area of the right triangle and less the area of the rectangle of the closet like this:
A= A(theater room) - A(right triangle) - A (closet)
A = x (x-4) -0.5 (8) (x - 4) - 4 (8)
Therefore, the correct equation to solve by area is option A
6ft 3in=75 inches
5ft=60inches
H=(height in inches)-60=75-60=15 hope thats right
X+2x=63 3x=63 x=21 21*2 is 42 so long is 42 and 21 is short
If you are adding all the angles, then it equals 180 degrees.
If you are looking for the missing angle out of 360.. then it is 180
