Question

The measure of two opposite angle of parallelogram are 3x-4 and 50-x . Find the angle of each

Answer 1

Opposite angles of a parallelogram are always equal.
A/q
3x-4 = 50-x
3x+x = 50+4
4x = 54
x= 13.5
1st angle = 3x-4= 40.5-4 = 36.4
2nd angle = 180-36.4 = 143.6 [ linear pair ]
3rd angle = 36.4 [ opposite angles are equal ]
4rd angle = 143.6 [opposite angles are equal ]
