Question

if two opposite angles of a parallelogram are (63-3x)degree and (4x-7)degree. find all the angles of the parallelogram.​

Answer 1

In parallelogram ABCD

let A= 63-3x

sum of opposite angles of triangle= 180

63-3x+4x-7=180

x= 110°

and the angle

B = 180-x

B = 70°

angle D = 180-angle B

D= 110°

Answer 2

Step-by-step explanation:

In parallelogram ABCD

let A= 63-3x

sum of opposite angles of triangle= 180

63-3x+4x-7=180

x= 110°

and the angle

B = 180-x

B = 70°

angle D = 180-angle B

D= 110
