can someone help me with triangle sum theory?

“Find m<1”
and it had two triangle on top of each other
1,2,22
and
3,20°,4
there’s also a 58 on the outside!
i think it’s supposed to be acute but i don’t know how to get there

a better description.

just list the angles and sides of both triangles. Use the usual notation such as
A,B,C for angles and a,b,c for the sides opposite them.

And how about asking a real question, rather than just something vague like triangle sum theory...
The only thing I know of is that the interior angles of a triangle sum to 180
at each vertex, the interior and exterior angles sum to 180
