A
How long is BC?

Answer 1

Answer:

BC = $\sqrt{12^{2} +12^{2} }$=12$\sqrt{2}$

Step-by-step explanation:

if the triangle is ABC and have part 12

and right angle from B and have an angle 45 then the third angle is 45 too

then we have another part is 12

and the BC = $\sqrt{12^{2} +12^{2} }$=12$\sqrt{2}$
