Answer:
18.3 = The third side
Step-by-step explanation:
Using Pythagorean Theorem; since the triangle is a right angled triangle.
Pythagorean Theorem states: A² + B² = C² (Where C is the hypotenuse, the line on the triangle opposite to the labeled right angle of the triangle, A and B would be the other 2 sides).
=> A² + B² = C²
=> 17² + B² = 25²
=> 289 + B² = 625
=> B² = 625 - 289
=> B² = 336
=> [tex]\sqrt{B^2}[/tex] = [tex]\sqrt{336}[/tex]
=> B = [tex]\sqrt{336}[/tex]
=> B = 18.3
Hope this helps!
