Answer:

5. A. <1 = 57°

6. C. <3 = 57°

Step-by-step explanation:

The upper portion and angle 1 made a linear pair. Linear pairs are supplementary angles. Meaning, their sum is 180°. To determine the measurement of angle 1, subtract the value of the upper portion to 180°. 180° - 123° = 57°

For number 6, angle 1 and angle 2 are vertical angles. Vertical angles are congruent. So measurement of angle 1 is equal to the measurement of angle 2.
