Question

plz answer fast and correct or else u are getting report​

Answer 1

Answer:

angle D is equal to 130°

Step-by-step explanation:

angle A+B = 180° {co interior angles}

3x -10+5x+30=180°

x=20°

Angle B=D=5×20+30=130° {opposite angles of a parallelogram are equal}

Answer 2

Answer:

A=C=50 degree & B=D=130 degree

Step-by-step explanation:

In parallelograme ABCD ,

<A =<C

<B =<D. .... ( opp. side of parallelograme)(i)

<A +<B +<C +<D = sum of all angle of parallelograme

2 (3x-10) + 2 (5x+30) = 360

6x - 20+ 10x + 60. = 360

160x + 40. = 360

10x. =360 - 40

10x. = 320

x. =20

therefor, A = C = 50 degree

B = D = 130 degree.
