Question

*Adjacent angles of parallelogram are of measure 2x & 7x then find the value of 'x'.*

1️⃣ 10
2️⃣ 20
3️⃣ 180
4️⃣ 90​

Answer 1

Answer:

2️⃣ 20

Step-by-step explanation:

Sum of adjacent angles are supplementary

2x+7x=180°

9x=180°

x=180°/9

x=20°

Answer 2

Step-by-step explanation:

$\huge\tt\fbox\purple{Given:}$

=>Measure of adjacent angle of a parallelogram is 2x and 7x.

$\huge\tt\fbox\purple{To Find:}$

=>The value of "x".

$\sf\overbrace{Concept \: refresher</p><p>}$

=>According to the question,

we know that sum of adjacent angles of parallelogram is 180°.

$\huge\tt\fbox\purple{Answer:}$

2x+7x=180°

9x= 180°

x=180/9

x= 20

Therefore, The value of "x" = 20°.
