Hint : Use pythagoras theorem here. $$\textbf{base}^2 + \textbf{perpendicular}^2 = \textbf{Hypotenuse}^2$$

@mathslover @Luigi0210 @Haiqa ahh, I messed of the formula sorry

75???

5 years ago
OpenStudy (luigi0210):

$a^2+b^2=c^2$ $100^2+b^2=125^2$$b^2=125^2-100^2$ $b=\pm \sqrt{5625}$

5 years ago
OpenStudy (anonymous):

its okay

5 years ago
OpenStudy (anonymous):

why is it i got 50.. @Luigi0210 @Haiqa @mathslover

5 years ago
OpenStudy (anonymous):

b=(125^2)-(100^2) 15625-10000=5625

5 years ago
OpenStudy (anonymous):

√5625=75

OpenStudy (luigi0210):

maybe you squared or subtracted wrong?
