Assume abc def. if ab = 12, bc = 15, and ac = 17, what is the length of ef?

Answer with explanation:

It is given that, ΔABC ≅ ΔDEF.

AB=12 cm

BC=15 cm

AC=17 cm

Also, you will observe that,

AB² + BC²

= 12² + 15²

=144 +225

=289

=AC²

Hence, ΔABC is right angled triangle,right angled at B.

Also, it is given that, ΔABC ≅ ΔDEF

So, DE=AB=12 units

BC=E F=15 units

D F=AC=17 units

So,E F=15 units

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?
