Find angles 1, 2, and 3

angle 1 = 51°,  angle 2 = 39°,  angle 3 = 90°

Step-by-step explanation:

Arrows on lines are used to indicate that those lines are parallel.

As the opposite lines are parallel, this indicates that angles 39° and angle 2 are alternate, which means they are equal.  So angle 2 = 39°

As the opposite lines are parallel, and we are given one of the interior corner angles as a right angle (90°), this means that all corner angles of the rectangle are 90°.  Therefore, angle 1 = 90° - angle 2 = 90 - 39 = 51°

Angle 3 is opposite to the right angle.  As the lines are parallel, angle 3 = 90°
