9

logan13 · Answer

how did you figure that out

mrnood · Answer

@logan13 @avinaysingh27 

it is not 9

logan13 · Answer

i know

mrnood · Answer

@logan13 
You are evidently studying the Pythagoras equation.

You have a right angled triangle

the longest side is opposite eth right angle and is called the hypotenuse

look at my diagram below - and write the equivalent numbers from your diagram..

|dw:1461780159530:dw|

you know the lenght of a and b

pythgoras equation is 

$$a ^{2}+ b ^{2} = c ^{2}$$

so work out c^2 from that equation

then take the squarerrot to find x

so

avinaysingh27 · Answer

I also have applies the same formula but got 9 previously which is wrong... The correct answet is sqrt(65) which is 8.06 rounding off to nearest tenth will make it 8..  hope its correct..

@avinaysingh27 
there is no need (and it is against the rules) to give complete answers

There is enough info above for @logan13 to work it out himself

@logan13 
that is not correct

Use the Pythagoras equation and show your working

what is a? 
what is a^2

what is b?
what is b^2

what is a^2 + b^2

what is c?

OK - that's enough
use my help 
show your work - the answer is easy if you follow the steps I suggest

If you can't be bothered - nor can I

i just dont know

mrnood · Answer

$$a ^{2}+b ^{2}=c$$

look at the diagram - find the equivalent sides

put the number in the equation

Ther ei s no point in me giving you the answer - you will have another question that requires you to 
a) make some effort
b) understand the Pythagoras equation
