Answer:
sum of adjacent angles of a parallelogram is 180°
therefore, angle a + angle b = 180°
Step-by-step explanation:
Let angle b be X
=>75°+X =180°
=>X=180°-75°
=>X=105°
now angle b is 105°
angle b =angle c=105°[opposite angles of a parallelogram are equal]
angle a=angle d =75°[opposite angles of a parallelogram are equal]
therefore the angles are 105°,75°,105°,75°

Answer:A + B + C + D = 360°
=>. A = C and B = D
=>. 2 A + 150 = 360
=>. A = 105°
So, the other three angles are 105°, 75 and 105°
