SOLUTION: Hypotenuse of right angle is 60 cm. if the leg is five cm longer than the other leg, what is lenght of the legs.
I know the formula is c^2= a^2 + b^2
60^2= x^2 + (x+5)^2
60

Question 148741: Hypotenuse of right angle is 60 cm. if the leg is five cm longer than the other leg, what is lenght of the legs.
I know the formula is c^2= a^2 + b^2
60^2= x^2 + (x+5)^2
60^2= x^2 + x^2 +10x +25
3600= 2x^2 + 10x + 25
Now what are we solving 4 x?
Answer by oscargut(2103) (Show Source): You can put this solution on YOUR website!
3600= 2x^2 + 10x + 25
then
2x^2+10x+25-3600=0
2x^2+10x-3575=0
=
=
then solutions are and
positive solution is
=39.85 (aprox)
So legs are 39.85 and 44.85 aprox
