Question

Anil is a student of class VII. His teacher explain the concept of line and angles. At the end of the chapter, his teacher conduct a 10 min test. The question was asked in the test is given below If AB || ML and ∠A = 32°, find the value of x. The answer given by Anil was 46°.

Answer 1

Angle A= angle MOA (alternate angles)

Angle MOA= 32°

angle MOA + angle x + angle LOB = 180° (Straight line)

angle x = 180°-(32°+142°)

or, angle x= 6°
