Hello!
You can use the Pythagorean Theorem
c is the hypotenuse which is the side across the right angle
a and b are the other sides
Put in the values you know
Square the numbers
Subtract 25 from both sides
Take the square root of both sides
a = 10.9
The answer is D) 10.9 centimeters
Hope this helps!

<u>ANSWER</u>: The centroid is (1,3)
<u>Explanation:</u>
The centroid is the intersection of the medians of the triangle.
So we need to find the equation of any two of the medians and solve simultaneously.
Since the median is the straight line from one vertex to the midpoint of the opposite side, we find the midpoint of any two sides.
We find the midpoint of AC using the formula;
The equation of the median passes through and
.
This line is parallel to the y-axis hence has equation
-------first median.
We also find the midpoint M of BC.
The slope of the median, AM is
The equation of the median AM is given by;
We use the point M and the slope of AM.
-------Second median
We now solve the equation of the two medians simultaneously by putting in to the equation of the second median.
Hence the centroid has coordinates
