Nnesha (nnesha):
you have to use Pythagorean theorem
\[\huge\rm a^2 +b^2 =c^2\]
remember c is the longest side of right triangle
so plug in a b c values then solve
if both sides are equal then yes :-)
OpenStudy (liv1234):
Wait so, 20^2+24^2=c^2?
Nnesha (nnesha):
substitute c value
OpenStudy (liv1234):
I don't think they are equal. So, I think the answer would be no.

But, would I be correct in saying that?
Nnesha (nnesha):
well use calculator

OpenStudy (liv1234):
I'm confused, so 20^2+24^2=30^2?1
Nnesha (nnesha):
31 not 30
OpenStudy (liv1234):
Oh oops.

now solve both sides
if both sides are equal then yes
if both sides are not equal then no
OpenStudy (liv1234):
Well, 31^2=961 and 20^2+24^2=976.
Nnesha (nnesha):
okay what about 20^2+24^2 = ??
take square and then add up
OpenStudy (liv1234):
20^2+24^2=976
Nnesha (nnesha):
yes so 31^2 ??

961
OpenStudy (liv1234):
So, the answer is no?
OpenStudy (anonymous):
A^2 or 20^2 is 400
B^2 or 24^2 is 576
C^2 or 31^2 is 961
400+576=976 not 961
Nnesha (nnesha):
yep
OpenStudy (liv1234):
Can you help me with another question?
