Answer:
The 3rd Graph
Step-by-step explanation:
This is tricky because the angle shown isn't refering to what is inside of it but what is not inside of it.
It's the third one and the last one are the only ones that make immediate sense.
Using the law of cosine for Triangle KJL, we can write:

Using the values of k,j and l, we can write:

Rounding to nearest integer, the measure of angle J will be 48 degrees.
So option B gives the correct answer
An estimate helps you place the decimal point because when you place 3.7 and 5.1 to multiply you have to count how many spaces of numbers there are. So the answer is 18.87.
The answer is c have a good day
