Question

please give me the Answer of this Question
​

Answer 1

p ll q all r

to find angle x

【A=angle】

so

A a+A x=180 {A in same side of trans}

Ax=180-60

Ax=120°

A b =A y {alt. A}

A y=40°

plz mark it as brainliest if u find it helpful

Answer 2

Answer:

Step-by-step explanation:

given that P║Q║R

y = 40 ° alternate int angle (∠QBC)

line P is a straight line therefore its for 180°∡

∴ 60°+ ∠ PAB = 180° and forms  (  linear pair )

∴ ∠PAB = 180- 60

 = 120°

and ∠PAB = x because of alternate int angles  

i hope this will help u .. please marks as thanks
