Question

Which expression gives the length of JK in the triangle shown below? (CAN SOMEONE SOLVE THIS)

Answer 1

do you know the pythagorean theorem?
a^2 + b^2 = c^2
where c is the longest side (opposite the right angle)

Answer 2

OKAY think it might be B ? is it

Answer 3

that would give you (jk)^2
do you know how to "get rid of the square"? you take the square root

Answer 4

in other words
if we have
\[ c^2 = a^2 + b^2 \]
we could do this
\[ \sqrt{c^2} = \sqrt{a^2 + b^2}\]
but \( \sqrt{c^2} \) is c so you get
\[ c= \sqrt{a^2 + b^2}\]

Answer 5

okay so the correct anwser is D right

Answer 6

Yes D is correct
