Question

find the values of the unknown ‘x’ and ‘y’in the following diagrams​

Answer 1

Answer:

in triangle PQR

y=60°

x=70°

and in triangle ABC

x=60°

y=90°

Answer 2

Answer:

y = 180-120 = 60 (linear pair)

x= 60+50+x= 180(by angle sum property of )

110+x=180

x=180-110

x=70

x=60(vertically opp. angles)

y=30+60+x=180(angle sum property of )

y =90
