Let four angles of given parallelogram taken in order be ∠A,∠B,∠C and ∠D respectively
Here opposite angles given ∠A=(3x−2) and ∠C=(x+48)
We know that opposite angles of a parallelogram are equal
∴3x−2=x+48
2x=50x=25∴3x−2=73∘∠A=∠C=73∘
Also we know that sum of two adjacent angles of a parallelogram is 180
∴∠A+∠B=180∘
73∘+∠B=180∘
∠B=107∘=∠D (Opposite angles are equal)
∴ All four angles of given parallelogram are 73∘,107∘,73∘,107∘
