1.

In a parallelogram ABCD, if ∠ = 2 + 25 ° ∠ = 3 − 5 °, find the value of x

Answer»

Answer:

Step-by-step explanation:

In ∥gm OPPOSITE angles are supplementary.

Therefore,

                ∠B+∠D = 180

  2x + 25 + 3x - 5 = 180

     x = 180 - 20 by 5 = 32

   

∠B = 2x + 25 = 2(32) + 25 = 89

∠D = 3x - 5 = 3(32) - 5 = 91
