Answer:

M1= 62 M2= 45 M3= 24

Explanation:

For angle 1:

180-118 = 62

Angle 2:

180- (73+62)

Angle 3:

part 1

180-73= 107

part 2

180-(107+49)= 24

Answer:

Explanation:

You have to solve for 1 before you do anything.

<1 + 118 = 180 The two left angles are supplementary

<1 +118-118=180-118

<1 = 62

Now you can go after angle 2

<1 + 73 + <2 = 180 All triangles have 180 degrees

62 + 73 + <2 = 180 Combine the left

135 + <2 = 180 Subtract 135 from both sides.

135-135+<2 = 180-135 Combine

<2 = 45

Angle 3 is a little trickier because the angle you need to find <3 is not labeled.

73 + x = 180

x = 180 - 73

x = 107

NOw you can find <3

107 + 49 + <3 = 180

156 + <3 = 180

<3 = 180 - 156

<3 = 24

I have left out the reasons for <3. Maybe you can supply them.
