Question

Find the value of 'x' in the figure.​

Answer 1

Answer:

x = 67

Step-by-step explanation:

It is given in the figure that

AB || CD

so, angle ABC = angle DCB = 73

In triangle DEC

angle CDE = 40

angle DCE = 73. ( DCB = DCE )

DCE + DEC + CDE = 180

73 + x + 40 = 180

x = 180 - 113

x = 67

Answer 2

Answer:

ab//cd

Angle abc=anglebcd [alternate angles]

anglebcd=73°

now, in triangle ced we have:

angledec+angelecd+angel cde=180°

x+40°+73°=180°[angleecd=anglebcd]

X+113°=180°

x=180°-113°

X=67°
