The hypotenuse of a right angled triangle is 25 cm. The other two sides are such that one is 5 cm longer than the other. Their lengths (in cm) are
15,20
By applying Pythagoras Theorem
AB2+BC2=AC2
x2+(x+5)2=625
2x2+25+10x=625
2x2+10x−600=0
x=15,−20
Side length of a triangle cannot be a negative.
Therefore, x=15
The other side lengths of a triangle are 15, 20
