Are these two triangles similar? How do you know?

Question

There are two triangles HMG and JMK
They are connected at the top point at M
H is on the bottom left, G is on the bottom right,
and M is at the top for triangle HMG

For triangle JMK
J is on the bottom right and K is on the bottom left
M is at the top for triangle JMK

Angle H measures 42°
Angle K measures 42°

(the triangles look the same, they are both connected
at M and only have one pair of angles that is known)

Thank You I have been having a little bit of a problem
on this question and your help is greatly appreciated!

Thank You so much! :)
