Answer 1

Step-by-step explanation:

AB = 12cm and BC=5cm

ABC is right angle triangle since ABCD IS RECTANGLE

AC=root(AB^2+BC^2)

=root(12^2+5^2)

=root(144+25)

=root(169)

=13

Answer 2

Ac =13

$in \: triangle \: abc \\ \\ by \: phytogores$

$ac {}^{2} = ab {}^{2} + bc {}^{2} \\ ac {}^{2} = 12 {}^{2} + 5 {}^{2} \\ ac {}^{2} = 144 + 25 \\ ac {}^{2} = 169 \\ ac = \sqrt{169} \\ ac = 13$
