Answer 1

Answer:

For the parallelogram to be a rectangle, at least one angle must be a right angle or a 90° angle, we know that:

    13x + 34° + 10x + 10° = 90°

=> 13x + 10x                   = 90° - 34° - 10°

=> 23x                            = 46°

=> x                                 = 46°/23 = 2°
