Question

Find the unknown angles in the following figures

Answer 1

Answer:

x=180-90+20= 70

y=20(v.o.a)

S=90

T=180-90+20=70

Answer 2

y=20°(vertically opposite angles)

PQR is a triangle

x=180-(90+20) [angle sum property in a triangle]

x=180°-110°

=70°=T

u+20°=180° [linear pair]

u=160°=v[vertically opposite Angles]
