. In given figure PQ lI RT. Find the values of a, b and c.Cl55°

Answer»

C=180-(80+55) =180-135 = 45

A is equal to C (because PQ and RT are parallel)A=45

B=55 (because PQ and RT are parallel)

c+80°+55°=180°.... {sum of angles of triangle is 180c=180°-135°=45°b=55°...... {alternate anglesa=c=45°..... {corresponding angle

80+55+c=180135+c=180C=180-135C=45

A equal c (beace ac is a corresponding angle) C=45

B equal q( because bq ias alternate angle) Hence b=55
