The length of the missing side of the triangle is 15.
How to calculate the length of the side of the triangle?
To calculate the length of the side of the triangle we must use the Pythagorean theorem:
b = [tex]\sqrt[]{(a^{2})-(b^{2} }[/tex]
In this formula we can replace the value of a and c with the distances of the other sides of the triangle.
b = [tex]\sqrt[]{(25^{2}) - (20^{2}) }[/tex]
b = [tex]\sqrt[]{(625) - (400)}[/tex]
b = [tex]\sqrt[]{225}[/tex]
b = 15
According to the above, the length of side b is 15.
