Angle 3 is equal to 65 degrees.
Given that
Lines m and n are parallel.
They are cut by transversal t.
We have to determine
What other angle is equal to 65 degrees?
According to the question
Lines m and n are parallel.
They are cut by transversal t.
By using vertical angle theorem;
The Vertical Angles Theorem states that vertical angles, angles that are opposite to each other and are formed by two intersecting straight lines, are congruent.
Vertical angles are always congruent.
Here the angle 3 and angle 65 are congruent to each other.
Hence, angle 3 is equal to 65 degrees.
