Answer:
10
Step-by-step explanation:
We know that the average of two numbers are the numbers divided by 2, right?
So the equation would be this
X + Y/2 = 12
x + y = 24, since 24 divided by 2 is 12.
You should add x (6) to 24 and wind up with 30
Now to get the average between those 3, divide by 30 by 3
you should get 10

The length of the side QR in the task content can be determined as; 12.22cm.
<h3>What is the length of the third side QR?</h3>
It follows from the task content that 2 lengths and one included angle are given in the task content. It therefore follows that the length of side QR can be evaluated by the cosine rule as follows;
QR² = 13² + 4² - (2×4×13×cos70)
QR = √149.4
QR = 12.22cm
