Question

In the given figure ABǁCD, find the value of x.​

Answer 1

Answer:

The value of X is 60°

Step-by-step explanation:

• Draw a line QR passing through O
• let X = angle 1 and angle 2
• angle CDO = angle 1 (DOR)
• = 20 = angle 1 (alternate angle)
• 140 + angle 2 = 180 (angle on the same side)
• angle 2 = 180 - 140
• angle 2 = 40
• Now, X = angle 1 + angle 2
• X = 20 + 40
• X = 60 °
