Answer 1

Answer: 73

Step-by-step explanation:

Angle B is 180-107=73

Angle 1 is equivalent to B and it is 73

Answer 2

Answer:

C.  ∠1 = 73°

Step-by-step explanation:

Angles on a straight line add up to 180°

Therefore:

⇒ ∠1 + 107° = 180°

Subtract 107° from both sides:

⇒ ∠1 + 107° - 107° = 180° - 107°

⇒ ∠1 = 73°
