Hint : Use pythagoras theorem here.
\(\textbf{base}^2 + \textbf{perpendicular}^2 = \textbf{Hypotenuse}^2 \)
mathslover (mathslover):
Recognize the base, perpendicular and hypotenuse from the figure. Plug in the values, find the value.
OpenStudy (luigi0210):
you may also know it as a^2+b^2=c^2 :P
OpenStudy (luigi0210):
Do you understand @effy_ ?

@Luigi0210 @mathslover @Haiqa I got 15.. i dont think thats correct
mathslover (mathslover):
Its right.
OpenStudy (anonymous):
Dont doubt yourself too much
mathslover (mathslover):
\(9^2 + 12^2 = c^2\)
\(81 + 144 = c^2\)
\(225 = c^2\)
\(c = \sqrt{225} = 15\)
mathslover (mathslover):
You're right effy. Good work :)

mathslover (mathslover):
Mam was just confusing you buddy, Usually elders try to analyze some one other, by confusing them with opposite answers. Have confidence on your work.

sorry c^2
OpenStudy (anonymous):
@mathslover ha ha :p
mathslover (mathslover):
:)
OpenStudy (luigi0210):

mathslover (mathslover):
It would not be 100.
OpenStudy (anonymous):
b² = c²-a²
OpenStudy (luigi0210):
It's a little too big
mathslover (mathslover):
Hint : Hypotenuse is 125 m, base is 100 m.
OpenStudy (anonymous):
hint hint c=hyp.

@mathslover @Luigi0210 @Haiqa ahh, I messed of the formula sorry
OpenStudy (anonymous):
75???
OpenStudy (luigi0210):
\[a^2+b^2=c^2\]
\[100^2+b^2=125^2\]\[b^2=125^2-100^2\]
\[b=\pm \sqrt{5625}\]
OpenStudy (anonymous):
its okay
OpenStudy (anonymous):
why is it i got 50.. @Luigi0210 @Haiqa @mathslover

OpenStudy (anonymous):
b=(125^2)-(100^2)
15625-10000=5625
OpenStudy (anonymous):
√5625=75
OpenStudy (luigi0210):
maybe you squared or subtracted wrong?
OpenStudy (anonymous):
@Luigi0210 subtracted wrong, haha. @Haiqa 75??
OpenStudy (anonymous):
