Solution

The opposite angles of a parallelogram are given as (3x2) and (50x).

Since, the opposite angles of a parallelogram are equal, then,

3x2=50x

3x+x=50+2

4x=52

x=13

(3x2)=(3(13)2)

=37

Therefore, one angle is 37, and its opposite angle is also 37.

It is known that the sum of adjacent angles of a parallelogram is 180, so,

Secondangle=18037

=143

Thus, the angles are, 37, 143, 37 and 143.
