Question

pls answer this step by step thank u​

Answer 1

Answer:

(A) 55°+angle ABC= 180 (linear pair)

angle ABC = 125°

and AOBC is a quadrilater so opposit angle sum is 180

125° + angle AOC =180

angle AOC= 55

X + AOC =360

X = 305°

(C)120° +angle ABC= 180

angle ABC =60

X + angle ABC= 180 ( linear pair)

X = 120°
