Answer:

x = 12

Step-by-step explanation:

The line joining the mid points of the non- parallel sides is parallel to the parallel sides and is equal to half the sum of the parallel sides, hence

5x - 20 = \frac{1}{2}(2x + 6 + 4x + 2)

            = \frac{1}{2}(6x + 8) ← distribute, giving

5x - 20 = 3x + 4 ( subtract 3x from both sides )

2x - 20 = 4 ( add 20 to both sides )

2x = 24 ( divide both sides by 2 )

x = 12

Line BD is tangent to circle O at C, Arch AEC = 299, and ACE = 93. Find Angle DCE.
VladimirAG [237]
In triangle ACE,
we know C=93,E can be calulated by using arch angle AEC...what ever that is....,using this we get  A=180-(E+93)

So, by alternate segment theorem, DCE= A.

thats all i can say.

if you could generate energy by fusing the hydrogen in solution a, how much of the solution would you need to generate the elect
iogann1982 [59]

Answer:

We know that:

Energy released by fusion of hydrogen in 1 liter of solution A = 7.6x10^10 J

Energy used daily in a certain family home = 3x10^4 J

(you did not write the units, so i suppose that are the same in both cases)

Then, if x is the number of liters of solution A used, the energy produced will be:

E(x) = x*7.6x10^10 J

And we want this equal to 3x10^4

then:

E(x) = x*7.6x10^10 J = 3x10^4 j

now we solve this for x.

x = (3x10^4 j)/(7.6x10^10 j) = 3.9x10^-7

Then you need to use 3.9x10^-7 L of solution a.
