Angle addition: a 90 degree angle is split into 35 degrees and x degrees. What is x?
Which equation models the missing angle in a 90 degree angle with one part 62 degrees?
- 62 - x = 90
- 90 - x = 152
- 62 + x = 90
Angle addition: a 120 degree angle is split into 49 degrees and x degrees. What is x?
Which equation models the missing angle in a 120 degree angle with one part 45 degrees?
- 45 + x = 120
- 120 - x = 165
- 45 - x = 120
Angle addition: a 120 degree angle is split into 34 degrees and x degrees. What is x?
Which equation models the missing angle in a 120 degree angle with one part 97 degrees?
- 120 - x = 217
- 97 + x = 120
- 97 - x = 120
Angle addition: a 120 degree angle is split into 91 degrees and x degrees. What is x?
Which equation models the missing angle in a 120 degree angle with one part 39 degrees?
- 120 - x = 159
- 39 - x = 120
- 39 + x = 120
Angle addition: a 120 degree angle is split into 63 degrees and x degrees. What is x?
Which equation models the missing angle in a 120 degree angle with one part 54 degrees?
- 54 + x = 120
- 120 - x = 174
- 54 - x = 120
