Leave your answer in simplest radical form

Step-by-step explanation:

The given triangle is a right triangle.

The m<K=45 degrees.

This means the measure of <L is  also 45 degrees.

This implies that;

|LM|=|KM|=7 units.

From the Pythagoras Theorem;

Option C is correct.

The answer is:

The third option,

Since we are working with a right triangle, we can use the following identity:

We are given:

Then, substituting and solving we have:

Hence, the answer is the third option,
