Question

plz answer this question and sove it please ​

Answer 1

Answer:

a=120°,c=120°,b=120°,d=60°

Step-by-step explanation:

according to theirs of parallelogram

a=180°-60°=120°(sum of 2 angles in straight line of a llo gram is 180)

c=120°(alternate interior angles)

b=120°(alternate interior angles(

d=60°(see reason no.1)

pls mark me brainlest

Answer 2

Answer: a= 120 degree  b = 60 degree c= 60 degree  d= 120 degree

Step-by-step explanation:

a + 60degree  = 180degree =>  a = 120degree     (  because the sum of co-interior angle is 180degree  )   60degree = b (alternate interior angles)     b= c = 60degree  (vertically opposite angles)    c + d = 180degree (linear pair) => 60degree + d = 180degree => d = 120degree
