Question

Answer of above question

Answer 1

angle b is 110degree, a=40degree,c=110degree(by corresponding angle prop..)

Answer 2

in this figure line yx and rq are parallel. and the ∆pyx and ∆prq are congruent in AAA. so angle a = angle q.angle c = angle b.


so , angle a = 40°
angle c = 180-(30+40)
= 110°
angle b=110°
