Ineed , i don’t understand how to do this.

m<1=44 m<2=136 m<3=44

Step-by-step explanation:

Angle 4 and angle 2 are directly across from each other. This means they fall under the vertical angles theorem which states that when the angles are across from each other they are the same. Ands 4 and 1 are supplementary angles which means that they are next to each other and form a straight line. Straight lines are 180 degrees so all you have to do is subtract and 4 from 180 to get 44. 3 is vertical from 1 and is also a supplementary angle so either way works to find this angle.
