Question

② find the values of
X and Y in the following parallelogram​

Answer 1

Answer:

6y=120 (opposite angles are equal)

y=120/6=20

5x+10+120=180 (Adjacent angles are supplementary)

5x+10=180-120=60

5x=60-10=50

x=50/5=10

All the properties mentioned in the bracket is applicable only to the parallelogram

therefore, X=10,  Y=20

Answer 2

Answer:

• x = 10°

• y = 20°

Step-by-step explanation:

Firstly Let's find y

• we know that Opposite angles of a parallelogram are equal

• So, 6y = 120

• y = $\tt \dfrac{120}{6}$

• y = 20°

Now, let's find x

• We know that sum of adjacent angles of A parallelogram are supplementary

• So, 120 + 5x + 10 = 180

• 5x + 130 = 180

• 5x = 180 - 130

• 5x = 50

• x = 10°

Property's used

• Opposite Angles of A parallelogram are equal.

• Sum of Adjacent angles of A parallelogram are supplementary
