ok i need someone to help me. I have the answer but dont know how to make the square root nto a decimal. I will try and draw it
a 24ft ladder is placed against a verticle wall. with the bottom of the ladder standing level 2ft fro the base of the building. how high up does the ladder reach. I got \[\sqrt{1}\] bt it has to b a decimal.how do I do that?
|dw:1402377963494:dw|
@tena32 I think your answer is wrong. I suggest you to give it another try.
Try to use pythogoras theorem, and if you did the same earlier then please check your calculations again.
this site was running funny and it didn't type my other number in. it was supposed to be 23 not 2
Even then you have done some mistake. Let the required height be h. Then according to the figure (that I drew), since, the triangle is a right angled triangle, I have, By pythogoras theorem, (height)^2 + (base)^2 = (hypotenuse)^2 |dw:1402378274592:dw|
@tena32, did you get it correct now ?
u need to apply Pythagoras theorem...... uderoot(2^2+24^2) solve it u get 24.08 ft
oh if it was supposed to be 23 instead of two just put 23 in Pythagoras theorem where i've put 2 and u'll get the right answer
\[\sqrt{23^{2}+24^{2}}\]
anwser is 33.24ft
