Question

In the figure PQRSvis a parallelogram, find the values of x & y​

Answer 1

Answer:

we know that sum of 4 sided polygon is =360°

• in the parallelogram sides are equal
• the opposite angles are equal

we can a name to parallelogram ABCD

in the fiqure

<B=110

so, <D=110

<A=180-110=70

so, <C=70

2x+10=70

2x+10-10=70-10

2x=60

x=60÷2=30

5x+10=110

5x+10-10=110-10

5x=100

x=100÷5=20
