Question

In the fig. PQRS is a Parallelogram. Find the value of x and y.​

Answer 1

Answer:

5x+10=110. (since opposite angles are equal)

=5x=110-10

=5x=100

=x=100/5=20

and 2y+10=180-110. (since angle opposite to this angle just lie adjacent to 110 and sum of adjacent angles is 180

hence, 2y +10=70

2y=70-10

=2y=60

=y=60/2=30

hence the value of x=20 and y =30

Plz mark me as brainliest

Answer 2

Step-by-step explanation:

In a parallelogram, opposite angles are equal

110=5x+10

110-10=5x

100=5x

100/5=x

x=20

Adjacent angles of a parallelogram are supplementary

110+(2y+10)=180

2y+10=180-110

2y=70-10

y=60/2

y=30
