Answer 1

Answer:

c°= 110° (corresponding angles are equal)

now, a°+c°=180°

a°+110°=180°

a=180°-110°

a°=70°

now a°+40°+x=180° (angle sum property of triangle)

70°+40°+x=180°

110°+x=180°

x=180-110°

x=70°

now, x°+b°=180°

70°+b=180°

b=180°-70°

b=110°

the example

Answer 2

As RS is parallel to PQ,

Angle PQS= Angle RSQ(alternate interior angles)

so,angle RSQ=25°

In Triangle PSQ By ASP

105°+25°+ Angle PSQ=180

there fore angle PSQ= 50

Now,Since RQ is parallel to PS,

Angle RQS=PSQ (alternate interior)

angle RQS=50

Since sum of opp angles of a quadrilateral is 180 degrees

105+AngleQRS=180

Angle QRS=75°

Therefore missing angles are

QRS=75

RQS=50
