we know
sum of all angles is 360 of a quadrilateral and opposite angle of parallelogram are equal
so let sides a b c d and 75 degree angle at a so opposite of angle a is c so c is also 75 degree
now solve for b and d
75 + 75 +b + d = 360
150 + b + d =360
b+ d=360 -150 =210
b, d are equal ( because paralleloram opposite sides are equal )
210 /2 =105 = b d
