Answer 1

Answer:

37°,143°,37°,143°

Step-by-step explanation:

Opposite angles of a parallelogram are equal to each other.

3x-2=50-x

3x+x=50-2

4x=52

x=52/4=13

Hence, measure of 1st and 2nd angles = 3x-2 =3×13-2=37°

Now,

Sum of adjacent angles of a parallelogram are equal to 180°

So, 180°-37°=143°

Hence measure of third and fourth angle of the parallelogram = 143°
