Question

How to solve this? Please help me !!!!!!!

Answer 1

Answer:

angle a = 117 reason vertically opposite angle

angle b = 117 reason alternate

angle c = 117 - 180 reason linear pair

= 63

angle d = 297 - 180 reason collinear

= 117

plz mark as brainliest plz plz plz yaar

thankyou

Answer 2

Answer:

a = 117° ( vertically opposite angles)

b= a = 117° ( alternative interior angles)

Since, b and c is a linear pair

b + c = 180°

c = 180 - 117

c = 63°

d = a = 117° ( opposite angles)
