Question

a parallelogram with its sides 3 cm and 2 cm and one acute angle 75 degree find its other angles

Answer 1

Other angles are 75,75 and 180-75 and 180-75. Because opposition angles are equal and adjacent are supplementary.

There forw angles are 75°, 105°, 75° and 105°.

Answer 2

/_ D + /_C = 180 (adjacent angle)
/_C= 180- 75
/_C= 105

/_C= /_A= 105 ( opposite angle )
/_D=/_B=75 (opposite angle )
