In the circle above, LM = 2 and KL = 6. What is the measure of MN?
A) 16
B) 10
C) 4
D) 8

C. 4

Step-by-step explanation:

We can use power of a point to solve this problem. From this, we can set up the equation:

MN^2 = LM x MK

MK would be the sum of LM and KL because of segment addition postulate. Therefore, we can say MK = 2 + 6 = 8

Now, we can substitute the values we have in the equation above:

MN^2 = 2 x 8

MN^2 = 16

MN = 4

step-by-step explanation:

so first find out how much each is worth.

quarter= 25 cents

dime= 10 cents

pennies= 1 cent

then multiply each by how much each is worth.

200                     150                   300

x                         x                     x   1

  25                       10              

                                  300

1000                     1500

+                          

4000                                      

5000                                  

then count 2 from the back and add a period.

$50.00

$15.00

$3.00

and then add them

  $50.00

+

  $15.00

+

    $3.00

$68.00

so sunghee has $68.00

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
