Given: EL- tangent, EK- secant <br> Prove: EJ·LK = EL·LJ
drek231 [11]

Answer:

This is possible.

Step-by-step explanation:

We can say that m<E=m<E, because of the Reflexive Property

Then, we have angles JKL and ELJ, which are equal through the peripheral angle theorem.

With these two angles, we can say that triangles ELK and EJL are similar, by the Angle-Angle Postulate (AA).

Then we can create this ratio through the Corresponding Parts of Similar Triangles Theorem, (CPST), \frac{LK}{LJ} =\frac{EL}{EJ}.

With this ratio, we can cross multiply to get the desired result

EJ·LK=EL·LJ

Hope this helps with your RSM problem

Yup, i caught ya.

I thought of a number, added 3 2/7 to it, then I multiplied the result by 1 1/2 , and got 6 5/7 . What was my number?
Arisa [49]
I got 25/21 or 1 4/21, but there’s a possibility I could’ve made a mistake in my math so you should double check it just in case.

How many millimeter are contained in 3 liters of fluid
vfiekz [6]
A millimeter is a one dimensional measurement whereas a liter is a three-dimensional measurement.  There is no equivalence between the two.

If you meant milliliter, that is also equivalent to a cm^3, of which there are one thousand in a liter.

1000ml=L or 1000cm^3=L

Can someone show me how to do it and the answer
Virty [35]

Answer:

B

Step-by-step explanation:

The equation of a circle is

(x-h)^2 + (y-k)^2 = r^2

h= 9, k = -7

r = 2, so r^2 = 4.

We now know that the equation must equal 4, so we can rule out answers A and C.

Plug in the values for h and k to get

(x-9)^2 + (y+7)^2 = 4

Choice B is correct!
