Question

If two lines intersect and one angle measures 25°, what are the measures of the other angles?

25
75
155
125

Answer 1

two angles measure 25° (including the one in the question)
the other two angles will measure 180-25=155°

Answer 2

If two lines intersect, and one angle is 25°, then we know the opposite angle is also 25°.

The other angles would be 180-25=155°

Answer=25° & 155°
