Question

class 9 maths pls solve it​

Answer 1

Answer:

x=23 by subtracting 57 from 180 as they both are linear pair ...and you will get your answer

Answer 2

let intersecting point o at line l and let s be intersecting point at line m.

As p||q and t as transverse so

<pot= <qso (corresponding angles) ...... (1)

As l||m and t as transverse so

<pot + 57°= <qso + x ° (corresponding angles) ....(2)

By (1) and (2) ,

x° = 57°
