Question

Can you please solve this issue ​

Answer 1

Answer:

y=60°and X=3.8

Step-by-step explanation:

angle ADE=angleY

so angleADE=180-120

angleADE=60° :. angle Y= 60°. (opposite angles of of parallelogram are equal)

perimeter =l×b

38= 10 × X

X=3.8

Answer 2

Answer:

x=3.8

y=60⁰

Step-by-step explanation:

l*b = 38 (given)

l*10=38

l=38/10

l=3.8m

angle 120+angle adc=180(linear pair)

120+adc=180

adc=180-120=60

angle adc=angle abc(as opposite angles are equal in a parallelogram )

so angle y= 60 ⁰
