Question

Two adjacent angles of a
parallelogram are (3x-2) and (3x -
10).Find x.​

Answer 1

Answer:

since they are adjacent

(3x-2)+(3x-10)=180°

3x+3x-12=180°

6x-12=180°

6(x-2)=180°

x-2=180°/6

x-2=30

x=28

Answer 2

Given:

• Two adjacent angles of paralleogram are (3x-2) and (3x-10) .

To Find:

• The value of x .

Answer:

We know that in a paralleogram , the sum of adjacent angles is equal to 180°.

So , the sum of these two given angles will be equal to 180°.

=> (3x- 2) + (3x-10) = 180°.

=> 3x + 3x - 2 - 10 = 180°.

=> 6x - 12= 180°.

=> 6x = (180+12)°

=> 6x = 192°

=> x = 192°/6

=> x = 32°.

Hence the value of x is 32°.
