Question

What is the length of the side BC of triangle ABC?
5 cm
8 cm
26 cm
32 cm

Answer 1

We have proven that they are congruent according to ASA.
BC \(\cong\)FE
Let's equate.

\(\Large \color{MidnightBlue}{\Rightarrow 3x + 2 = 4x - 6 }\)
\(\Large \color{MidnightBlue}{\Rightarrow 3x = 4x - 8 }\)
\(\Large \color{MidnightBlue}{\Rightarrow 8 = x }\)

Now plug-in the value
3(8) + 2
24 + 2
26
