Question

in parallelogram abcd ∠A =3 x+15°, ∠B =3x-25°.Find x.​

Answer 1

Answer:

We know that in a parallelogram ,

        The sum of  adjacent angles is 180°

                      => ∠A + ∠B = 180°

                      => 3x + 15 + 3x - 25 = 180

                      => 6x - 10 = 180

                      => 6x = 190

                      => x = 31.67° (Ans.)

Answer 2

Step-by-step explanation:

• Here, In llgm ABCD
• Angle A = 3x + 15° and Angle B = 3x - 25°
• We know that Angle A + Angle B = 180°
• So, (3x+15°) + (3x-25°) = 180°
• 3x + 15 + 3x - 25 = 180
• 6x = 180 + 25 - 15
• 6x = 190
• x = 190/6 = 31.6°
