Which statement is true about the angles below?

A. If angle 1 is 110°
, then angle 3 is also 110°
because they are adjacent angles.
If angle 1 is 110 degrees, then angle 3 is also 110 degrees because they are adjacent angles.

B. If angle 1 is 110°
, then angle 3 is 70°
because they are complementary angles.
If angle 1 is 110 degrees, then angle 3 is 70 degrees because they are complementary angles.

C. If angle 1 is 110°
, then angle 3 is 70°
because they are supplementary angles.
If angle 1 is 110 degrees, then angle 3 is 70 degrees because they are supplementary angles.

D. If angle 1 is 110°
, then angle 3 is also 110°
because they are vertical angles.
