Question

in parallelogram PQRS , find the value of a,b and c .

(please see the figure)
please solve it step by step
please.............. ​

Answer 1

Answer:

r=110 c=r(ver opp angles)

b+c=180 (linear pair)

b=70

a=r(opp sides of parellogram) since a= 110

Answer 2

Answer:

angle R = 110 degree

angel C= angle R =110 degree (VOA)

angle B = B+C = 180 (linear pair)

B + 110 =180

B = 70 degree

angle A = A+B = 180 (supplementary angle )

A+70=180

A= 110 degree
