Angle addition: a 120 degree angle is split into 64 degrees and x degrees. What is x?
Which equation models the missing angle in a 120 degree angle with one part 65 degrees?
- 120 + 65 = x
- 120 - x = 185
- 65 + x = 120
- 65 - x = 120
Angle addition: a 150 degree angle is split into 124 degrees and x degrees. What is x?
Which equation models the missing angle in a 150 degree angle with one part 108 degrees?
- 108 + x = 150
- 108 - x = 150
- 150 - x = 258
- 150 + 108 = x
Angle addition: a 120 degree angle is split into 35 degrees and x degrees. What is x?
Which equation models the missing angle in a 120 degree angle with one part 61 degrees?
- 120 - x = 181
- 120 + 61 = x
- 61 - x = 120
- 61 + x = 120
Angle addition: a 180 degree angle is split into 115 degrees and x degrees. What is x?
Which equation models the missing angle in a 180 degree angle with one part 119 degrees?
- 119 + x = 180
- 119 - x = 180
- 180 + 119 = x
- 180 - x = 299
Angle addition: a 210 degree angle is split into 172 degrees and x degrees. What is x?
Which equation models the missing angle in a 150 degree angle with one part 110 degrees?
- 150 + 110 = x
- 150 - x = 260
- 110 + x = 150
- 110 - x = 150
