If ΔMNO≅ΔGHI, m∠M=25°, and m∠O=50°, then what is m∠H?

I'm pretty sure you take the measure of angle M and the Measure of angle O and add them with x = to 180.

50+25+X=180

x = 105

I'm not positive since I can't draw out the triangles at this time. just double check your class notes and check the steps you did and apply them to your homework.

What even is this? I'm confused as ever!
