Answer 1

Answer: m 1= 62 m 2= 45 m 3=58

Step-by-step explanation:The angles of a triangle equal 180. You subtract the angles that you know from 180 and the answer you're left with is the answer. The last one has an extra step because it only gives you one angle so to find the angle right next to 73 you subtract 73 from 180 which is 107 and then you subtract 49 from that which is 58.

Answer 2

Angle 1 is 62

Angle 2 is 45

Angle 3 is 24

Step-by-step explanation: from

To get angle 1 you subtract 118 from 180 (180-118) and get 62

For angle 2 you subtract 62 and 73 from 180 (180-62-73) and get 45

For angle 3 you first subtract 73 from 180 (180-73) and get 107 then subtract 107 and 49 from 180 (180-107-49) and get 24

You subtract everything from 180 because with straight lines they are equal to 180 degrees and triangles are also equal to 180 degrees
