Question

find all the angles of parallelogram in abcd in the figure​

Answer 1

Answer:

bh

=Xx4x=180

4x²=180

x=4x/180

=45

,

Answer 2

Step-by-step explanation:

angle DAB=2x

reason opposite angles of a parallelogram are equal

In triangle ADB,

2x+4x+3x=180

reason sum of all angles of a triangle is 180 degree

9x=180

x=180/9=20

All angles

Angle A= Angle C=2x=40 degree

Angle CBD= AngleADB

reason interior alternate angles

angle B=3x+4x=7x=140 degree

Angle B=Angle D= 140 degree

reason reason opposite angles of a parallelogram are equal

Angle A=40°

angle B=140°

angle C=40°

angle D=140°
