SOMEONE HELP ME PLEASE I NEED AN EXPLANATION A GOOD ONE
AND ANSWER

Find the length of MK if JK=36, JL=48, and JN=60.

The length of MK is 9

Explanation:

The length of the sides are , ,

We need to determine the length of MK

From the figure, we can see that JMN is a triangle and KL is parallel to MN.

Then, by side - splitter theorem, we have,

where ,

The length of LN can be determined by subtracting JN and JL.

Thus, we have,

The length of LN is

Substituting the values , and in , we have,

Multiplying both sides by 12, we have,

Thus, the length of MK is 9

-4

step-by-step explanation:

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
