Question

Find the values of the variable a given the transformation is an isometric

Answer 1

The transformation shown in the question shows that

$\begin{gathered} 48^0\approx6b \\ 2a\approx24 \end{gathered}$

This means that 2a is congruent to 24

Thus

$\begin{gathered} 2a=24 \\ \\ a=\frac{24}{2} \\ \\ a=12 \end{gathered}$

Hence,

a=12
