Answer 1

To determine the similarity between the two triangles, we first need to find the missing angles in both triangles.

For triangle \(ABC\):
- Given: \(m\angle A = 47^\circ\) and \(m\angle B = 36^\circ\).
- The sum of angles in a triangle is \(180^\circ\):
\[
m\angle C = 180^\circ - m\angle A - m\angle B = 180^\circ - 47^\circ - 36^\circ = 97^\circ.
\]

For triangle \(GHJ\):
- Given: \(m\angle G = 36^\circ\) and \(m\angle J = 97^\circ\).
- Calculate the missing angle \(H\):
\[
m\angle H = 180^\circ - m\angle G - m\angle J = 180^\circ - 36^\circ - 97^\circ = 47^\circ.
\]

Now we have:
- Triangle \(ABC\) has angles: \(47^\circ, 36^\circ, 97^\circ\).
- Triangle \(GHJ\) has angles: \(36^\circ, 47^\circ, 97^\circ\).

Since both triangles have the same angles, we can conclude:

\[
\triangle ABC \sim \triangle GHJ.
\]

Thus, the appropriate response is:

\[
\triangle ABC \sim \triangle GHJ.
\]
