1. MathsWatch question

the right angled has three sides with the lenghts of (x-1) and (x+4) and 6
The right angle
Hypotenuse=6 cm
height side= (x+4)
base=(x-1)
Question= find the value of x? 3.sf
2. (X-1)^2 + (X+4)^2 = 6^2

There's a start, try and work it out from there
3. thank you i got x=1.928 3sf
and -4.928 3sf
how do you think like that these kind of stuff dont come into my head
i was think of multiply the parenthesis then add 6 and then factorising it
4. What have you been learning recently? Pythagoras?

it's just pythagoras. if you're not sure about what to do, just do something which seems sensible. you know it's a right angled triangle and you have all sides so just sub them into pythagoras.

you either see it, or you don't
