@Nnesha

use pythagoras theorem...
\[hypotenuse ^{2} = base ^{2} + perpendicular ^{2}\]
OpenStudy (anonymous):
here you have hypotenuse = 20 and base = 14
Nnesha (nnesha):
same like last one same formula
do it first and let me know what you get

and you have to find the value of perpendicular...
so put the given value u will get the answer
Nnesha (nnesha):
|dw:1427581455758:dw|
\[\huge\rm a^2 +b^2 =c^2\]
again longest side which is hypotenuse is c
OpenStudy (narissa):
is it 24.41?
OpenStudy (narissa):
@Nnesha
OpenStudy (narissa):
i put 200*200 and 14*14 and got 596 and then the square root is 24.41 is that right?

\[a^2 + b^2 =c^2\]
replace variables by their values and show me ur work
OpenStudy (narissa):
this is hard i showed u how i was doing it
OpenStudy (narissa):
@StudyGurl14
Nnesha (nnesha):
no i'm saying how did you substitute
Nnesha (nnesha):
a = ??
b =?
c=??
