Question

In a parallelogram ABCD, Angle A=x°,Angle B=(3x+20)°. Find x, Angle C and Angle D.​

Answer 1

Answer:

not all only one 111.000000 20+3x

Answer 2

Answer:

A=C=40,C=D=140

Step-by-step explanation:

ln a parallogram opposite angles are equal

A+B+C+D=360

X+3x+20+X+3x+20=360

8x+40=360

8x=360-40

8x=320

X=320/8=40

A=40,C=40

B=D=3x+20=3*40+20=140

a

A+B+C+D=40+40+140+140=360
