Answer:
im a scorpio but my sister in law is a taurus... :)
Step-by-step explanation:
Hey there,
Angle AEB + Angle CED = 180 degrees (vertically opposite angles)
(5x-10) degrees + (3x + 40) degrees = 180 degrees
5x -10 + 3x + 40 = 180 degrees
5x + 3x= 180 + 10 - 40
8x = 150
x = 150 / 8
= 18.75 degrees
Angle AEB = (18.75 x 5) - 10
=83.75 degrees.
Hope this helps ^_^

Answer:
x = 9
Step-by-step explanation:
Well, let's solve it!
x - 9 = 0
Let's add 9 to both sides to isolate the variable and maintain equality.
We end up with :
x = 9 since -9 and 9 cancel out and 0 + 9 = 9.
Answer:
8 inches
Step-by-step explanation:
Surface area of a prism is:
S = 2A + Ph
where A is the area of the base, P is the perimeter of the base, and h is the height of the prism.
The base is a square, so A = s² and P = 4s:
S = 2s² + 4sh
Given that S = 512 and h = 12:
512 = 2s² + 4s(12)
512 = 2s² + 48s
256 = s² + 24s
0 = s² + 24s - 256
0 = (s + 32) (s - 8)
s = -32, s = 8
Since s must be positive, s = 8 inches.
Answer:
21
Step-by-step explanation:
8 * 2 = 16
5 * 2 = 10
68 - 16 = 52 - 10 = 42.
The perimeter of the square is 42.
42 / 4 = 10.5. 10.5 is the length of a side.
10.5 * 2 = 21.
